Brief information about the 67 sources detected at a confidence level higher than 4 sigma between 1988 and 1998 is provided. X-ray properties and characteristic spectra of different types of sources are briefly described in the reference paper. This table was created by the HEASARC in April 2011 based on the <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/PAZh/26/355">CDS catalog J/PAZh/26/355</a> file table1.dat.
