R help - Aug 2012 - How do I find the apparent magnitude of a galaxy from a FITS file?

Greetings!
I am still new to R but have been asked to look at doing astronomy with R.
I have a FITS file which contains an optical telescope image (it can be
viewed in SAOimageDS9).
I need to estimate the magnitude of a galaxy... and eventually other optical
sources.

How do I find the apparent magnitude of a galaxy from a FITS file?

Hello,

A search using sos::findFn('fits') returned package FITSio as number
three.
It would enable you to read FITS files. As for the question, how do you 
do what you want to do, I don't know.

Hope this helps,

Rui Barradas
