Accessing Winter 2013 coadd FITS files

The server lsst-web.ncsa.illinois.edu provides access to the data. The entire namespace can be explored by pointing your browser to:

http://lsst-web.ncsa.illinois.edu/lsstdata

The individual FITS files are stored in a directory hierarchy using the following scheme:

http://lsst-web.ncsa.illinois.edu/lsstdata/dr-w2013/deepCoadd/[ugriz]/<tract>/<patch>/coadd-[ugriz]-<tract>-<patch>.fits

where

  • [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")

Examples

wget http://lsst-web.ncsa.illinois.edu/lsstdata/dr-w2013/deepCoadd/r/3/7,2/coadd-r-3-7,2.fits

Data Sizes

  • Individual coadd files are 40MB (uncompressed).
