Description:
The 1000 foot Arecibo reflector was used with a multiple feed system
to map the region 0h < RA < 12h, -2d < DEC < +18d at 611 MHz. The
observations were made in meridian transit mode using an array of ten
line feeds with the electric polarization vector in the east-west
plane. The beam power pattern of each feed was approximately Gaussian
and circulary symmetric with a half power beam width of about 12.6
arcmin. A source list was produced containing fluxes and positions of
3118 radio sources stronger than 0.35 Jy. The source list is complete
for strong, unresolved sources. However it is not intended to be
complete for objects highly resolved by the 12.6 arcmin beamsize. The
list's lower limit of 0.35 Jy is about 5 times the average sky
confusion.
The survey was calibrated to the KPW (Kellermann, Pauliny-Toth, and
Williams 1969ApJ...157....1K) flux scale. The secondary calibrators
were ten sources measured at Arecibo at 606 MHz based on the KPW scale
(Condon, Niell and Jauncey 1971). Marked by an asterisk in Table 2,
these sources were too few to be used alone to calibrate all of the
declination strips. Since a more complete list of good calibration
sources did not exist at 611 MHz, the fluxes of 159 additional sources
were independently measured accurate to about 7 percent at Arecibo in
the Fall of 1973. Table 2 gives their assigned fluxes. These sources
were tied to the KPW scale through the ten secondary calibrators.
