haro29_ubvcalib.txt
The following calibration format can be used directly in
IRAF.digiphot.photcal.invertfit. The instrumental magnitudes
mU, mB, and mV are -2.5*log(counts/s)+25.
For the these images, the average parameters for UBV are the following:
Airmass---1.03, 1.03, 1.07
Integration time (s)---1800, 2000, 900
Pixel scale (arcsec)---0.61, 0.61, 0.61
