Description:
    The 2.2um (K) scan (table1) was made on the Mt. Stromlo 1.9m telescope
    with the MSO IR-photometer, during several observation sessions in
    1981, at sideral rate with a 12arcsec aperture; the rows of the scan
    were spaced by 6arcsec in declination, and were on the average
    65arcmin long.
    Detailed JHK photometry of a sample of the brightest sources (table 2)
    was obtained during later observing sessions in 1981 and 1982.
    The photometric results are given in the AAO system (Jones & Hyland,
    1980MNRAS.192..359J)

  B = Several observations of the source.
  C = Faint source confused with a brighter one.
  D = These sources are out of the limits of our scan.
