Data Release v0.9

The observations, reduction procedure, PSF maps, and point source sensitivity analysis are presented in Labbé et al., in prep. Please cite Labbé et al., ApJS (2015) if you make use of these data in your publications.

The IRAC science images are drizzled onto a 0.3 arcsec grid using a pixfrac = 0.2 and are placed on the same astrometric system and reference grid as the CANDELS/GOODS-S WFC3 mosaics (Koekemoer, A. M. et al., 2011, ApJS, 197, 36).

The units of the science mosaics are relative to a zeropoint of AB = 20.04. The units of the exposure time maps are seconds.

The PSF maps are supplied in a multi-extension fits file, including a sample program which demonstrates how to reconstruct the PSF at any location in the images.

A download script is provided which uses the command line tool curl to download the entire dataset (including separate reductions of all 272 AORs) and can be edited to download only the files needed.

The images are hosted on the Infrared Science Archive (IRSA) of the Infrared Processing and Analysis Center (IPAC).
