I have finished the imexam task and get the value of FWHM and STDDEV, but when i precise the apphot package, there is something wrong with it.
In task datapars, i have set fwhmpsf=5, sigma=8, datamin=0, datamax=65000, readnoise, epadu, exposure, airmass and so on.
In task photpar, i have set apertures, zamag.
in task fitskypar, i have set annulus, dannulus.
In task centerpars, i have set cbox.
After that,
>disp 093ab01.imh
>phot 093ab0.imh
and "enter"
but the software tell me " cannot open file (093ab01.imh.coo.0) " i donnot known what is wrong with it, please give me a hand.thanks.

Normally, image names beginning with a number are problematic since the CL syntax tries to interpret these as numeral values rather than passing these on to the task. Because you are able to display the image I'm not convinced this is the problem, but because this name is used as a root for the coords file in the task it might not be interpreted correctly.

I'd suggest trying to IMCOPY the image to something like 'foo.imh' and trying again: If that works it might well be the numeric name problem, otherwise, are you sure the file exists in the current directory (i.e. does the ".0" extension make sense?)?
