Abstract:
A 2380MHz survey of bright galaxies in the declination range from zero
to +37° has been made at Arecibo. It is complete to a photographic
magnitude of +14.5mag in all right ascensions except between 11h 30min
and 13h 00min, where the limit is +14.0mag. Four hundred fifty-six of
the 2095 galaxies observed were detected above 15mJy, a cutoff which
is the quadratic sum of 5 times the 2mJy rms confusion and 3 times the
3mJy receiver noise on a single scan.
Description:
The observations were made during the two intervals 1975 August
28-1975 September 11 and 1975 December 21-1976 January 3.
