ADC_Keywords: Radio sources Abstract: A surveys of compact (<1") radio sources exhibiting interplanetary scintillation were conducted at 102MHz on the Large Phased Array of the Lebedev Institute of Physics. The surveys cover a 0.047 steradian area of the 7C survey in the direction RA=6h28m and DE=45° and a 0.097-steradian area in the direction RA=10h28m and DE=41°. A total of 395 scintillating radio sources in a 0.144 sr region were detected. File Summary:

Note (1): Objects are identified in Simbad as: [AT96] HHMMSS+DDMM or [AT96] HHMMSS+DDMM.m in table1.dat [ATI98] HHMMSS+DDMM in table2.dat Note (2): Special notes: A: compact source, more than 50% of total flux is contained in the scintillating component, B: the source with the name from the 7C catalog in parenthesis impedes the estimation of the parameters for the scintillating source. C: the parameters for the scintillating source may be affected by the source in parenthesis. D: the source identification is ambiguous, and the scintillating source may belong to several of the 7C radio sources E: scintillating source is not identified with any 7C radio source. F: complex region, it is impossible to extract the source. G: uncertain identification of the source. H: uncertainty in the source detection. If a substantial integrated flux density, S, (>3Jy) is observed at the location of a scintillating source, it is given in the notes. A symbol ':' after flux value indicates uncertainty in the source detection.
