Subtract background noise from CDFS and ELAIS #211

The difference between the radio images of the two regions need to be investigated. One easy check is to see whether background radio noise is the cause.

Two files have be uploaded to cloudstor. The two files are the noise pattern for each field. As you can see they are indeed different. ELAIS_I_allch_noise.fits.gz and CDFS_I_allch_noise.fits.gz

Two astronomical software packages to view FITS image files are:

SAO DS9
KVIS

I haven't subtracted the noise from the two fields. This may be a good think to implement in the code. Have an input for the noise map.
