Abstract:
A database containing 618 active and star-forming (A/SF) galaxies and
564 normal galaxies in a 120°x6° wide strip crossing the
North Galactic Pole was constructed in order to compare the global
properties of "active" galaxies against a control sample of "normal"
galaxies. This database combines a literature and catalog search with
new optical measurements from the Fpg (red) and Jpg (blue) band images
of the STScI Digitized Sky Survey (DSS). We provide alternative names,
accurate coordinates, morphological type, activity classes, red and
blue apparent magnitudes, 2MASS near-infrared J-H and H-K colors,
apparent diameters, axial ratios, position angles, and number counts
of neighboring objects in a circle of radius 50kpc. We also present
an atlas of 103 interacting and merging systems among these galaxies.
In this sample, all merging and interacting galaxies are A/SF objects.
The near-infrared colors of the sample galaxies are independent
parameters and do not correlate with activity level or any other
parameter of the galaxies.
Description:
We took the galaxies from a CfA2 strip (See Huchra et al., 1990,
Cat. VII/193) 8h≤RA≤17h and 26.5°≤DE≤32.5°, and
cross-checked this sample with all known possible sources of active
or star-forming galaxies.The optical measurements of these galaxies
are based on the digitized F- and J-band images extracted from the
photographic plates obtained for the second Palomar Observatory Sky
Survey (POSS-II; Reid et al., 1991PASP..103..661R 1991PASP..103..661R).

the LINERs. Starburst and HII nuclei respectively are indicated by
"SB" and "HII". Galaxies with Wolf-Rayet features in their spectra
are indicated with the symbol "WR". X-Ray sources are indicated as
"X" and radio galaxies as "R".
