MAPS
----
There are 4 sets of maps in each band.  These sub-maps are made
from unique data, and therefore share the same signal but
have unique noise properties.  Therefore, in the cross correlations 
of sub-maps, noise should not be correlated.
1/f noise is high-pass filtered at 0.2 hz.  These large scales can b
recovered though the use of the Transfer Function, which is also included.

The maps are as follows:

GOODS_wide_NCMR_XPS_*_*_flux.fits  : Flux maps in Volts
GOODS_wide_NCMR_XPS_*_*_noise.fits : Noise maps in Volts
GOODS_wide_NCMR_XPS_*_*_hits.fits  : Hits maps, inversely proportional to sqrt(Noise).
Flux maps with sources above 500, 400 and 300 mJy removed:
GOODS_wide_NCMR_XPS_*_*_flux_subsource_cut_*mJy.fits : In MJy/sr

To convert from Volts to MJy/sr apply the following calibration values:
calibration_250 = 2.73e6
calibration_350 = 2.86e6
calibration_500 = 1.16e6
