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)
