J/A+AS/90/327  1612MHz OH survey of IRAS point sources (te Lintel Hekkert+ 1991)
1612 MHz OH survey of IRAS point sources

Description: 2703 sources have been observed at the 1612MHz transition
    of OH, and 783 OH/IR stars were detected; 597 of these detections are
    new discoveries. The IRAS sources were detected on the basis of their
    IRAS fluxes at 12, 25 and 60um. The survey is 70% complete for IRAS
    sources in the Southern hemisphere (Dec←10°) with F(12um)>3Jy,
    with IR colors log(F25/F12)>-0.2 and log(F60/F12)<0.6

    Note that the file catalog.dat contains all observed sources,
    with a flag indicating the detection or non-detection; the
    detected sources only are listed in the printed version of Table2,
    while sources without detectable 1612MHz emission are listed in
    Table3 (on microfiche)

Note (1): The detection flag is
          1 = non-detection
          2 = likely detection
          3 = standard profile
Note (2): for single-peak detections, the values are in VL and SL,
          (VH and SH are set to 0)


History:
  * December 1992: the electronic version of the table was e-mailed to
    CDS by Hekkert te Lintel.
  * April 1998: Non-measured sources without OH-Name were removed.
    The documentation (this ReadMe file) was revised and completed.
