The SRELICS data set contains the IRAC mosaics from the 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. 

Data reduction is similar to that described in Bradac et al. (2014). Mosaics
were created using MOPEX. PSFs were created by stacking point sources in 
the field for each channel (see Huang et al. 2016, 
http://adsabs.harvard.edu/abs/2016ApJ...817...11H, for details). All 
mosaics are made using pixfrac = 0.1 to attain better spatial resolution.

The folders are structured 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 doesn't usually produce images of the same dimension in both 
channels. In that case, both images were resampled 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).
