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 1980MNRAS.192..359J)
