- Title:
- Surface Photometry of Hydra I Galaxies. I.
- Short Name:

- Description:
- Surface photometry was made for 137 galaxies on a UK Schmidt plate whose center is located at the center of the Hydra I (A1060) cluster of galaxies. For 133 of 137 galaxies the photometric parameters such as total magnitude, equivalent radius, concentration indices, and mean surface brightness were obtained. The total magnitudes were compared with those in the literature to check the accuracy of the present data. The estimated accuracy in the total magnitudes is about 0.1 mag at most for majority of the galaxies. This catalog is an updated version from the published paper.

- Description:
- We present surface photometry and metallicity measurements for 104 nearby dwarf galaxies imaged with the Advanced Camera for Surveys and Wide Field and Planetary Camera 2 aboard the Hubble Space Telescope. In addition, we carried out photometry for 26 galaxies of the sample and for Sextans B on images of the Sloan Digital Sky Survey. Our sample comprises dwarf spheroidal, irregular and transition type galaxies located within ~10Mpc in the field and in nearby groups: M81, Centaurus A, Sculptor and Canes Venatici I cloud. It is found that the early-type galaxies have on average higher metallicity at a given luminosity in comparison to the late-type objects. Dwarf galaxies with MB>=-12 to -13mag deviate towards larger scalelengths from the scalelength-luminosity relation common for spiral galaxies, h{prop.to}L^0.5^_B_.

- Title:
- Surface photometry of nearby field galaxies

- Description:
- We have obtained integrated spectra and multifilter photometry for a representative sample of ~200 nearby galaxies. These galaxies span the entire Hubble sequence in morphological type, as well as a wide range of luminosities (M_B_=-14 to -22) and colors (B-R=0.4-1.8). Here we describe the sample selection criteria and the U, B, R surface photometry for these galaxies. The spectrophotometric results will be presented in a companion paper (Cat. <J/ApJS/126/331>).

- Surface photometry of NGC 5907

- Description:
- Intrigued by the initial report of an extended luminosity distribution perpendicular to the disk of the edge-on Sc galaxy NGC 5907, we have obtained very deep exposures of this galaxy with a Schmidt telescope, large-format CCD, and intermediate-band filters centered at 6660 {AA} and 8020 {AA}. These two filters, part of a 15-filter set, are custom designed to avoid the brightest (and most variable) night skylines. As a result, our images are able to go deeper with lower sky noise than those taken with broadband filters at similar effective wavelengths: e.g., 0.6 e^-^ arcsec^-2^ s^-1^ for our observations versus 7.4 e^-^ arcsec^-2^ s-1 for the R-band measures of Morrison et al. (1994AJ....108.1191M). In our assessment of both random and systematic errors, we show that the flux level where the errors of observation reach 1 mag arcsec^-2^ are 29.00 mag arcsec^-2^ in the 6660 {AA} image (corresponding to 28.7 in the R band) and 27.4 mag arcsec^-2^ in the 8020 {AA} image (essentially on the I-band system)

- Title:
- Surface photometry of Virgo ellipticals
- Short Name:
- J/ApJS/182/216
- Date:

- Publisher:
- CDS
- Description:
- New surface photometry of all known elliptical galaxies in the Virgo cluster is combined with published data to derive composite profiles of brightness, ellipticity, position angle, isophote shape, and color over large radius ranges. These provide enough leverage to show that Sersic logI{prop.to}r^1/n^ functions fit the brightness profiles I(r) of nearly all ellipticals remarkably well over large dynamic ranges. Therefore, we can confidently identify departures from these profiles that are diagnostic of galaxy formation. Finally, we verify that there is a strong dichotomy between elliptical and spheroidal galaxies. Their properties are consistent with our understanding of their different formation processes: mergers for ellipticals and conversion of late-type galaxies into spheroidals by environmental effects and by energy feedback from supernovae.

- Title:
- Survey around the North Ecliptic Pole at 11 cm
- Short Name:
- J/A+AS/75/67
- Date:

- Publisher:
- CDS
- Description:
- This catalog contains a survey of a rectangular area of 10x6 degrees in galactic coordinates (95.5{deg} < l < 101.5{deg} ; 28{deg} < b < 38{deg}) in the radio continuum in the direction of the north ecliptic pole (RA=18h, Dec=66.5{deg}) at 11.1 cm wavelength. The survey was conducted with the 100m radio telescope of the Max Planck Institut fur Radioastronomie. 469 sources were detected with an integrated flux density greater than 11 mJy, and with an angular resolution of 4.35'. The survey is believed to be complete to at least the 35 mJy level and can be used for comparison with deep surveys in other wavelengths of this area.

- Title:
- Survey for ionization in neutral gas galaxies. I.
- Short Name:

- Publisher:
- CDS
- Description:
- We introduce the Survey for Ionization in Neutral Gas Galaxies (SINGG), a census of star formation in HI-selected galaxies. The survey consists of H{alpha} and R-band imaging of a sample of 468 galaxies selected from the HI Parkes All Sky Survey (HIPASS). The sample spans three decades in HI mass and is free of many of the biases that affect other star-forming galaxy samples. We present the criteria for sample selection, list the entire sample, discuss our observational techniques, and describe the data reduction and calibration methods. This paper focuses on 93 SINGG targets whose observations have been fully reduced and analyzed to date.

- Description:
- We use the first data release from the Survey for Ionization in Neutral-Gas Galaxies (SINGG) H{alpha} survey of HI-selected galaxies to study the quantitative behavior of the diffuse, warm ionized medium (WIM) across the range of properties represented by these 109 galaxies.

- Title:
- Survey of 108 E-S0 galaxies
- Short Name:

- Date:

- Publisher:
- CDS
- Description:
- A survey has been performed of the morphological and photometric properties of 108 E-S0 galaxies out of a complete sample of 112: this sample is built from the Revised Shapley-Ames Catalogue (RSA) keeping objects with {delta}>-10deg and V_0_<3000km/s, rejecting SB0's and Local Group dwarfs. The data were mainly derived from our CCD observations at Observatoire de Haute-Provence: the camera allowed fields of 4x7arcmin (or 7x7 from the last run), the seeing being generally in the 2-3arcsec FWHM range. The measurements include the isophotal analysis according to Carter's (1978) principles, and the photometric profiles along the two main axis. Opposite semi-axis are measured separately to detect asymmetries.
