Abstract:
    A Catalog of X-ray sources as observed by the TTM/COMIS telescope
    onboard the Mir-Kvant observatory is presented. Brief information
    about the 67 sources detected at a confidence level higher than
    4σ between 1988 and 1998 is provided. X-ray properties and
    charateristic spectra of different types of sources are briefly
    described.

Note (1):  the typical value of the mCrab is 2-3x10-11erg/cm2/s
           (0.2-0.3fW/m2) in this energy range.

  * 04-Sep-2000: prepared by Veta Avedisova [INASAN]
  * 07-Apr-2011: fixed errors in the description of table1 above
      (communication from Steve Drake, HEASARC): position in J2000 
      (was originally specified as 1950), and definition of the mCrab
      removed. A table 2 most likely related to a paper by Taranova
      (2000AstL...26..404T = 2000PAZh...26..472T) has been removed.
