Hi,Can anyone please tell me where I will be able to change the photometry output format of allstar task to more decimal digits.
I have already done that for the aperture photometry output in the file "apwres2.x" but cannot find the file that writes the output for psf or allstar.Do I also need to change it in the psf output file if it is read by allstar?Thank you

Jaco[/quote:a73332ba35]The systematics in allstar, in my experience, are huge. I'm curious why you need more decimal digits as they are probably physically meaningless.

I need photometry down to milli-magnitudes, so 4 decimal places in the phot output is needed. I did psf and aperture photometry. The aperture photometry is now fine but I need to get the magnitude output of psf photometry also to 4 decimal digits.So do you know which file I need to edit in order to change the output?Thanks
