Sir,
I got some problem in reducing the data with package apphot. I have been trying to use both qphot and phot task within apphot but some warning message came like below----
[b:a17f269814]Warning: Graphics overlay not available for display device.[/b:a17f269814]
Moreover after going to ds9 and hitting "s" by selecting some bright star i got message like these------
[b:a17f269814]m67u1bf.fits     INDEF    INDEF     INDEF    INDEF    INDEF      0     0  err
m67u1bf.fits     INDEF    INDEF     INDEF    INDEF    INDEF      0     0  err

m67u1bf.fits     INDEF    INDEF     INDEF    INDEF    INDEF      0     0  err[/b:a17f269814]And also, when i put "r" it is showing----
[b:a17f269814]No coordinate list[/b:a17f269814]
Actually, amongest phot and qphot which one will give me best result for aperature photometry.
Kindly help at your earliest.
Thanking you,
Yours faithfully,
