n3738_jhkcalib.txt
The following calibration format can be used directly in
IRAF.digiphot.photcal.invertfit. The instrumental magnitudes
mJ, mH, and mK are -2.5*log(counts/s)+25.
For the these images, the average parameters for JHK are the following:
Airmass---1.16, 1.16, 1.43
Integration time (s)---25.92, 5.92, 2.90
Pixel scale (arcsec)---1.5, 1.5, 1.5
