This folder contains the IRAC mosaics from Marusa's SRELICS program (4 epochs
per cluster) plus DDT program (2 epochs per cluster) for all RELICS clusters.
The full-depth mosaics will reach ~ 5.4 hours per channel per cluster. I am
making mosaicks using Russell Ryan's IDL script that wraps around MOPEX. I am
also making empirical PSFs by stacking point sources in the field for each
channel. All mosaics are made using pixfrac = 0.1 to attain better spatial
resolution.

The folder is structure as 
cluster_name/ch[12]

where the images are inside the folders of each channel under each cluster. The
file names should be self-explanatory. The only thing to note is that, due to
the design of the observations, ch1 and ch2 don't have the same footprint,
and MOPEX (the software I use to make mosaics) don't usually produce images
of the same dimension in both channels. In that case, I resampled both images
using SWarp so that both channels are on the same pixel grid. The resampled
images have the file names *_swp_drz.fits (for science image) and 
*_swp_wht.fits (for weight maps).

If you have questions about these mosaics, please contact me at
