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). -- Kuang-Han Huang, 03/28/2017 [edited 11/28/2018, IRSA]
