[R] 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? -- View this message in context: http://r.789695.n4.nabble.com/How-do-I-find-the-apparent-magnitude-of-a-galaxy-from-a-FITS-file-tp4639907.html Sent from the R help mailing list archive at Nabble.com.

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,
