for the WHT
We have estimated the limiting magnitude using
band filters for a S/N ratio equals 5 and good observing conditions
seeing of 0.75 arcsecond. The sky brightness is taken as
arcsec, J=16.0 mag/sq. arcsec, H=14.0 mag/sq. arcsec and K=13 mag/sq.
We also show the variation of limiting magnitude as function of
We have estimated the limiting magnitude in
using R=1000 , for a S/N ratio equals 3 and good observing conditions
seeing of 0.5 arcsecond (slit width matches the seeing).
