Abstract
We present H I 21-cm line observations of 543 galaxies at low galactic latitude in the Galactic Anticenter region of the Zone of Avoidance ( 4(h) less than or equal to alpha less than or equal to 8(h), 0 degrees less than or equal to delta less than or equal to 37 degrees). The sa mple comprises 147 catalogued objects (from UGC, CGCG, MCG, and IRAS) still missing a redshift measurement and a list of 369 objects selecte d from an extensive optical compilation of galaxy candidates in this a rea. The spectra were acquired using the 305-m Arecibo telescope and c over a velocity range from -350 to +13800 km s(-1) at a resolution of about 16 km s(-1). 196 galaxies were detected, 59 of the catalogued on es and 137 from the optical compilation. The H I derived properties ar e presented, as is a discussion regarding the redshift distribution in this region. Our data seem to be consistent with a link across the Zo ne of Avoidance between the Pisces-Perseus supercluster and Abell 569. (C) 1997 American Astronomical Society.
