The BIMA Survey of Nearby Galaxies (BIMA SONG)
BIMA SONG is a systematic imaging study of the 3 mm CO J = 1 --> 0molecular emission within the centres and discs of 44 nearby spiralgalaxies on size scales of a few hundred parsecs (6-9``). The overallgoal of the survey is to study the role of molecular gas in theevolution of spiral galaxies. To this end, BIMA SONG addresses 1) thedistribution and physical conditions of the molecular gas in galacticdiscs and its relation to star formation, 2) the effects of a stellarbar on the kinematics of molecular gas, including the possible inflow ofgas along a bar, and 3) the distribution and role of molecular gas inthe central few hundred parsecs of active and quiescent galaxies. Thesource list includes all (except M33 and M31) 44 galaxies of Hubbletypes Sa-Sd, with declinations δ > -20^°, visual magnitudesB < 11.0, velocities v_hel < 2000 km s^-1, and inclinations i <70^°. Beyond the specific scientific questions we will address, thissurvey will provide a unique database for astronomers who study galaxiesat all wavelengths.
| Galaxy coordinates. II. Accurate equatorial coordinates for 17298 galaxies
Using images of the Digitized Sky Survey we measured coodinates for17298 galaxies having poorly defined coordinates. As a control, wemeasured with the same method 1522 galaxies having accurate coordinates.The comparison with our own measurements shows that the accuracy of themethod is about 6 arcsec on each axis (RA and DEC).
