- Description:
- All Herschel observations are processed through an automatic pipeline, which corrects a number of instrumental artifacts. The Highly Processed Data Products (HPDP) have gone through additional interactive processing, and represent an improvement over the standard products. HPDP from Herschel's Photoconductor Array Camera and Spectrometer (PACS) are available for JScanam maps, Unimap maps, and Red Leak Spectra.

- Description:
- The Panchromatic Hubble Andromeda Treasury is a Hubble Space Telescope Multi-cycle program to map roughly a third of M31's star forming disk, using 6 filters covering from the ultraviolet through the near infrared. With HST's resolution and sensitivity, the disk of M31 will be resolved into more than 100 million stars, enabling a wide range of scientific endeavors.

- Description:
- During the years 2004 to 2017, the Palomar 60 inch telescope (P60) operated as a fully robotic facility to obtain targeted optical observations of gamma-ray burst (GRB) afterglows and other transient events. An automated pipeline reduced the data in real time. The raw, calibration, and pipeline-processed data are available here.

- Planck 030 GHz Survey
- Short Name:

- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- Planck is ESA's third generation space based cosmic microwave background experiment, operating at nine frequencies between 30 and 857 GHz and was launched May 2009. Planck provides all-sky survey data at all nine frequencies with higher resolution at the 6 higher frequencies. It provides substantially higher resolution and sensitivity than WMAP. Planck orbits in the L2 Lagrange point. These data come from Release 1 of the Planck mission. <p> The original data are stored in HEALPix pixels. SkyView treats HEALPix as a standard projection but assumes that the HEALPix data is in a projection plane with a rotation of -45 degrees. The rotation transforms the HEALPix pixels from diamonds to squares so that the boundaries of the pixels are treated properly. The special HealPixImage class is used so that SkyView can use the HEALPix FITS files directly. The HealPixImage simulates a rectangular image but translates the pixels from that image to the nested HEALPix structure that is used by the HEALPix data. Users of the SkyView Jar will be able to access this survey through the web but performance may be poor since the FITS files are 150 to 600 MB in size and must be completely read in. SkyView will not automatically cache these files on the user machine as is done for non-HEALPix surveys. </p> Data from the frequencies of 100 GHz or higher are stored in a HEALPix file with a resolution of approximately 1.7' while lower frequencies are stored with half that resolution, approximately 3.4'.

- Description:
- Planck is ESA's third generation space based cosmic microwave background experiment, operating at nine frequencies between 30 and 857 GHz and was launched May 2009. Planck provides all-sky survey data at all nine frequencies with higher resolution at the 6 higher frequencies. It provides substantially higher resolution and sensitivity than WMAP. Planck orbits in the L2 Lagrange point. <p> These data come from the legacy Release 3 of the Planck mission. <p> These products include polarization information available to visualize in several ways. The data contain Stokes parameters I, Q, and U, and in addition to these, it is possible to visualize the polarized intensity PI=sqrt(Q^2+U^2) and the polarization angle PA=1/2atan(U/Q). Note that at their native resolution of a few arcmin (depending on the frequency), these polarization data will appear very noisy. In order to visualize the polarization information, it is highly recommended that the data be resampled with the "Clip (intensive)" sampler and the result smoothed. That sampler will average all the data points within a given output pixel rather than the more common nearest neighbor. It will do this averaging before computing either PI or PA to reduce the effects of the noise. This sampler is set as the default for this survey. If the output pixel resolution is not significantly larger than the resolution, a smoothing of the output pixels will also be necessary. <p> Note also that Q and U are defined relative to a given co-ordinate system, in this case Galactic, and following the CMB convention (not the IAU); see https://lambda.gsfc.nasa.gov/product/about/pol_convention.cfm. This means that they will appear to vary rapidly near the pole of that coordinate system. The PI and PA will be computed correctly for any position on the sky. <p> The original data are stored in HEALPix pixels. SkyView treats HEALPix as a standard projection but assumes that the HEALPix data is in a projection plane with a rotation of -45 degrees.

- Publisher:
- The GAVO DC team
- Description:
- These observations cover five star-forming regions in the Andromeda galaxy (M31) with optical integral field spectroscopy. Each has a field of view of roughly 1 kpc across, at 10pc physical resolution. In addition to the calibrated data cubes, we provide flux maps of the Hβ, [OIII]5007, Hα, [NII]6583, [SII]6716 and [SII]6730 line emission. Line fluxes have not been corrected for dust extinction. All data products have associated error maps.

- PSPC summed pointed observations, 0.6 degree cutoff, Intensity
- Short Name:

- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- The ROSAT PSPC surveys were generated by <i> SkyView </i> as mosaics from publically available PSPC observations. The surveys include all data available through March 1, 1997. This includes the vast majority of ROSAT PSPC observations. Filter observations and observations taken during the verification phase in 1991 were not included in either set. The details of the generation of the surveys are discussed in a <a href="https://skyview.gsfc.nasa.gov/help/pspc_generation.html"> companion document</a>. Basically the counts and exposure from all observations were added and then an intensity map was generated as the ratio of the two. <p> The smaller cut-offs allow users to distinguish point sources in fields where a bright source may have been towards the edge of one observation and near the center of another. In these cases the source appears fuzzy due to the poor resolution of ROSAT near the edge of the field of view. This comes at the cost of a substantial reduction in the fraction of the sky covered. Counts and exposure maps are included for users who may need this information (<i>e.g.</i>, to do statistical analysis). <p> The global organization of the surveys is similar to the IRAS survey. Each map covers an area of 2.5&#176;;x2.5&#176;; with a minimum overlap of 0.25&#176;;. To cover the entire sky would require over 10,000 maps. However due to lack of coverage only approximately 4000-6000 maps are actually populated. Users asking for reqions where there is no ROSAT coverage may get a blank region returned. <p> Detailed information regarding the creation of the ROSAT suveys can be found in the <a href="https://skyview.gsfc.nasa.gov/help/pspc_generation.html"> ROSAT PSPC Generation Document</a>.
