Description:
A meter-wave survey of the sky region north of declination +30 
degree has been carried out with the Miyun Synthesis Radio Telescope
(MSRT), Beijing Astronomical Observatory, at 232 MHz. 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.

Notes to table 2:
  Local S/N is calculated in the way of maximum(peak flux, integral flux)/
  (local noise). the epochs of R.A. and Dec. are 1950.0
