Description:
A meter-wave survey of the sky region north of declination +30°
has been carried out with the Miyun Synthesis Radio Telescope
(MSRT), Beijing Astronomical Observatory, at 232MHz. It is a
moderately deep survey. The observations were made between January
1985 and December 1993. The covered sky area is divided into 156
fields of view. Basically all adjacent fields are separated by
8 degree angular distance. Fields #54, #56, #115, #116, have no data
yet. A catalog of 34462 radio sources is given in Table 2. Table3
shows the information on the 152 fields of view.

Note (1): The name is based on a truncated B1950 position; a suffix
A, B, C or D differentiates sources with identical
truncated positions.
Note (2): Local S/N is calculated in the way of
maximum (peak flux, integral flux)/(local noise)
