Description

This is a collection of images of 113 nearby galaxies assembled at the Department of Astrophysics, Princeton University. All are large, bright and well resolved. Observations with CCDs are form Palomar Observatory (31 galaxies) and from Lowell Observatory (82 galaxies). Images from Palomar are available in 3 photometric bands: Thuan-Gunn g, r and i; images from Lowell are in two bands: J and R.

We present a digital catalog of images of 113 galaxies in this paper. These galaxies are all nearby, bright, large and well resolved. All images were recorded with charge coupled devices (CCDs) at the Palomar Observatory with the 1.5 meter telescope and at the Lowell Observatory with the 1.1 meter telescope. At Palomar we used the Thuan--Gunn g, r and i photometric bands to take 3 images each of 31 spiral galaxies; at Lowell we used the B_J and R bands (2 images per galaxy) of the photometric system by Gullixson et al. (1995) to observe 82 spirals and ellipticals. The galaxies were selected to span the Hubble classification classes. All data are photometrically calibrated with foreground stars removed. Important data on these galaxies published in the "Third Reference Catalog of Bright Galaxies" (RC3) are recorded in the FITS file headers. Princeton University Press will soon publish the data on CD-ROM.
