- Title:
- Galactic Planetary Nebulae Catalog
- Short Name:
- Plan.Neb.
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This is the 1992 Version of the Strasbourg-ESO Catalog of Galactic Planetary Nebulae (Acker et al.1992). It includes 1143 true and probable planetary nebulae (from Table 1 of the publication) and 347 objects whose status was still unclear and were thus classified among the "possible" planetary nebulae (from Table 2 of the publication); it does not include 330 objects once considered as possible planetary nebulae but which the authors have since rejected (listed in Table 3 of the publication). The designation system for the planetary nebulae listed in this catalog follows the recommendations of IAU Commission 5 (Astronomical Nomenclature) with the structure: "PN Glll.l+bb.b", where PN means "Planetary Nebula", G stands for "Galactic Coordinates", and lll.l+bb.b are the galactic longitude and latitude respectively, truncated to one decimal place. Copies of the complete catalog, including the Finding Charts (Part I) can be ordered from the ESO Information Service, Karl-Schwarzschildstr. 2, D-85748 Garching bei Muenchen, Germany. This database was created by the HEASARC in May 2001 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/V/84">CDS Catalog V/84</a>, tables main.dat, diam.dat, dist.dat, dista.dat, hbeta.dat, iras.dat, nir.dat, radio.dat, vel.dat, cstar.dat, and pospn.dat.

- Title:
- Green Catalog of Galactic SNRs (June 2017 Version)
- Short Name:
- SNR(Green)
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This catalog of known Galactic supernova remnants (SNRs) is an updated version of the catalogs of Galactic SNRs presented in detail in Green (1984, 1988), in summary form in Green (1991, 1996, 2004, 2009), and on the Web (versions of 1995-July, 1996-August, 1998-September, 2000-August, 2001-December, 2004-January, 2006-April, 2009-March, and 2014-May). [Note that the version published in Green (1996) was produced in 1993.] This June 2017 version of the catalog contains 295 SNRs, and is based on results published in the literature up to the end of 2016. The basic summary data included in this catalog for each SNR are its designation, position, angular size (in arcminutes), type, flux density at 1 GHz, spectral index, and any other names by which it is known. Notes on these parameters, on possible remnants not included, and on questionable SNRs that are listed in this catalog, are given in the full version of the catalog on the Web at <a href="http://www.mrao.cam.ac.uk/surveys/snrs/snrs.info.html">http://www.mrao.cam.ac.uk/surveys/snrs/snrs.info.html</a> It should be noted that there are serious selection effects which apply to the identification of Galactic SNRs (e.g., Green 1991, 2004, 2005, 2009, 2014), so that care should be taken if these data are used in any statistical studies. This version of the Green Catalog of Galactic Supernova Remnants was ingested at the HEASARC in July 2017. It is based on the Catalogue of Galactic Supernova Remnants, 2017 June version, <a href="https://cdsarc.cds.unistra.fr/ftp/cats/VII/278">CDS Catalog VII/278</a>, file snrs.dat, obtained from the CDS at <a href="http://cdsarc.u-strasbg.fr/ftp/cats/VII/278/">http://cdsarc.u-strasbg.fr/ftp/cats/VII/278/</a>.

- Title:
- Lynds Catalog of Bright Nebulae
- Short Name:
- Lynds(Bright)
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The Lynds' Catalog of Bright Nebulae lists the coordinates of the center of the cloud, the dimensions of the nebulae as measured on the photograph on which it appeared at its brightest, the area of nebulosity in square degrees, color as compared between the blue and red Palomar plates, a brightness index on a scale from 1 to 6, an identification number that indicates the complexity of the nebulosity, and a cross reference to NGC (Cat. <VII.1>), Index Catalogue (IC), Sharpless (1959) Catalogue of HII Regions (Cat. <VII/20>), Cederblad (1956) Catalogue of Diffuse Galactic Nebulae, and Dorschner and Gurtler (1963). This database originates from the NASA/ADC CD-ROM "Selected Astronomical Catalogs Vol. 1", dated 09-July-1992. The CDS made several corrections to this and added the LBN sequence number. The current HEASARC version of this table was revised in February 2001 and is based on the CDS version. This is a service provided by NASA HEASARC .

- Title:
- Lynds Catalog of Dark Nebulae
- Short Name:
- Lynds(Dark)
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This catalog is an updated version of the original version of the Lynds' Catalog of Dark Nebulae that was published in 1962. The catalog was based on a study of the red and blue prints of the National Geographic - Palomar Observatory Sky Atlas. The catalog contains positions for the centers of dark nebulae or clouds found by Lynds, values for the cloud sizes in square degrees, visual estimates of their opacity, and cross-identifications to Barnard Objects which are associated with the tabulated clouds. This HEASARC version of the LDN Catalog was created in June 1997. It was derived from <a href="https://cdsarc.cds.unistra.fr/ftp/cats/VII/7A">CDS Catalog VII/7A</a> obtained from <a href="https://cdsarc.cds.unistra.fr/ftp/cats/VII/7A/">https://cdsarc.cds.unistra.fr/ftp/cats/VII/7A/</a>. Please refer to the CDS <a href="https://cdsarc.cds.unistra.fr/ftp/cats/VII/7A/ReadMe">"Historical Notes"</a> for details regarding the lineage of this version. Additional information provided in the HEASARC documentation was taken from the original published version of this catalog. This is a service provided by NASA HEASARC .

- Title:
- MASH Catalogs of MASH Planetary Nebulae
- Short Name:
- MASHPNCAT
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The first part of the Macquarie/AAO/Strasbourg H-alpha Planetary Nebula Catalog (MASH) contains 903 new true, likely and possible Galactic planetary nebulae (PNe) discovered in the AAO/UKST H-alpha survey of the southern Galactic Plane. The combination of depth, resolution, uniformity, and areal coverage of the H-alpha survey has opened up an hitherto unexplored region of parameter space permitting the detection of this significant new PN sample. The second part, MASH-II, consists of over 300 true, likely and possible new Galactic PNe found after re-examination of the entire AAO/UKST H-alpha survey of the Southern Galactic Plane in digital form. Over 240 of these new candidates were confirmed as bona fide PNe on the basis of spectroscopic observations. This HEASARC table contains all 1238 objects from the combined MASH and MASH-II catalogs. This table was created by the HEASARC in April 2010 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/V/127A">CDS Catalog V/127A</a> files mash1.dat and mash2.dat.

- Merged Catalog of Reflection Nebulae
- Short Name:
- REFNEBULAE
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- Several catalogs of reflection nebulae have been merged to create a uniform catalog of 913 objects. It contains revised coordinates, cross-identifications of nebulae and stars, as well as identifications with IRAS point sources. The HEASARC has endeavored to render all identifications of the nebulae in the various catalogs according to the styles recommended by the Dictionary of Nomenclature of Celestial Objects. This table was created by the HEASARC in October 2012 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/399/141">CDS Catalog J/A+A/399/141</a> file table1.dat.

- Title:
- Milky Way Project First Data Release IR Bubble Catalog
- Short Name:
- MWP1BUBBLE
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table contains a new catalog of 5106 infrared bubbles created through visual classification via the online citizen science website 'The Milky Way Project' (MWP). Bubbles in the new catalog have been independently measured by at least five individuals, producing consensus parameters for their positions, radii, thicknesses, eccentricities and position angles. Citizen scientists - volunteers recruited online and taking part in this research - have independently rediscovered the locations of at least 86% of three widely used catalogs of bubbles and H II regions while finding an order of magnitude more objects. 29% of the bubbles in the Milky Way Project catalog lie on the rim of a larger bubble, or have smaller bubbles located within them, opening up the possibility of better statistical studies of triggered star formation. This online resource of the <a href="http://www.milkywayproject.org/">Milky Way Project</a> provides a crowd-sourced map of bubbles and arcs in the Milky Way, and will enable better statistical analysis of Galactic star formation sites. This table is the first data release of the MWP IR Bubble Catalog: the authors anticipate a future release of a second, refined catalog incorporating better data-reduction techniques. This table was created by the HEASARC in March 2013 based on the <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/424/2442">CDS Catalog J/MNRAS/424/2442</a> files mwplarge.dat and mwpsmall.dat.

- Title:
- Sharpless H II Regions
- Short Name:
- Sharpless
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This database table is derived from data contained in the Sharpless Catalogue of H II regions. The original catalog was published in 1959 in the Astrophysical Journal Supplement Series (number 41, pages 257- 280). The original card deck was in the 026 punch and this was converted to a 029 deck. Many of the quantities in this version of the catalog were not in the published catalog. The epochs of the precessed equatorial coordinates were determined empirically from the data as given on the computer cards. This is a service provided by NASA HEASARC .
