Accessing Winter 2013 coadd FITS files

The server provides access to the data. The entire namespace can be explored by pointing your browser to:

The individual FITS files are stored in a directory hierarchy using the following scheme:[ugriz]/<tract>/<patch>/coadd-[ugriz]-<tract>-<patch>.fits


  • [ugriz] is a single filter id from the indicated list (currently only "r")
  • <tract> is the LSST skymap tract id (currently 0 or 3)
  • <patch> is the LSST skymap patch id (of the form "xxx,yyy")



Data Sizes

  • Individual coadd files are 40MB (uncompressed).
