J/AZh/77/21        102.5MHz Survey             (Dagkesamanskii+, 2000)

A sky survey at 102.5MHz: radio sources at declinations 27.5°-33.5° and 67.5°-70.5° Dagkesamanskii R.D., Samodurov V.A., Lapaev K.A. <Astron. Zh. 77, 21 (2000)> =2000AZh....77...21D =2000ARep...44...18D
ADC_Keywords: Radio sources ; Surveys Description: The results of observations on the Large Phased Array of the Lebedev Physical Institute made as part of a survey of northern sky at 102.5 MHz are reported. Survey source lists for declination ranges 27.5-33.5 deg. and 67.5-70.5 deg. are given, together with their coordinates, flux densities and identifications with 4C objects. In total, there are 920 sources with flux densities S(102.5)≥3.0 Jy in the two zones, which cover over 0.73 steradians. File Summary:
