WFC3 ERS M83 Data Products

The drizzled mosaics described here are available as High-Level Science Products (HLSP) via the Multimission Archive at STScI (MAST). The filenames and descriptions of Version 2 drizzled science mosaics are listed below. This filenaming convention makes these HLSP files compatible and queryable with MAST and the Hubble Legacy Archive (HLA). Note that the early (version 1 or "v1" in filenames) images used to produce the publications are also available for download. These files contain only the south field. But the team later combined both fields using the best calibrations available at the time of this HLSP data release. We recommend the use of these version 2 ("v2" in filenames) files for most subsequent analyses.

The WFC3 UVIS mosaics have the native detector scale of 0.0396 arcsec/pixel. The enhanced-resolution IR mosaics have a scale of 0.0792 arcsec/pixel, which is 62% of the IR detector scale (and exactly twice the UVIS scale). For each drizzled science mosaic (drz_sci), there is a corresponding exposure weight map (drz_wht), and also small preview JPEG images available on the MAST website.

All Files may be downloaded via the browser or via ftp (ftp archive.stsci.edu; cd /pub/hlsp/wfc3ers).
