DRAVG members, please give here a summary of mirroring requirements at your institution, with a link to a more detailed page if necessary.

= Some numbers as background info =

Estimates made by Gene:

 * 1 copy of the static sky images is ~350 TB
 * At the end of the survey, the dvo database of the 3pi sky will contain 100e9 distinct measurements of 5e9 distinct objects, making up 50-60 TB of data.
 * 90% of the objects are in the 10% of sky that is in the plane. I.e., if you are not interested in the galactic plane, you "only" need ~6 TB for storing all of the catalogs that interest you.

See [wiki:Mirroring Mirroring] for more (rough) estimates, in particular of bandwidth required.

= Requirements =

 * '''MPIA/MPE'''
   * '''Andromeda, Milky Way, brown dwarfs and quasars''' at MPIA (M31, 3pi): cmf files and/or dvo catalogs and corresponding postage stamps images ASAP.
   * For brown dwarfs & quasars: initially, the high-galactic-latitude sky will be enough; the brown dwarfs want the entire sky once proper-motions can be determined.
   * For quasars (and maybe brown dwarfs, too?):
     * izy stacks as soon as possible after data are taken 
     * forced photometry in all other bands at the locations of all z and y-band detections
   * '''MDS''': raw, chip, chip (background restored), camera, warp, warp (background restored), stack (unconvolved), diffs 
   * '''3pi''': for one sky patch: raw, chip, camera, stack (convolved and unconvolved) 
   * '''Pan-Planets''': raw, chip, chip (background restored), camera, warp, warp (background restored) and diffs for all images of the crowded STS replacement field taken in demo month 
   * '''PAndromeda''': raw, chip (background restored), camera, warp (background resored) and diffs for all existing M31 observations
 * '''Belfast''' 
   * '''3pi survey''' ''from MHPCC'': cmf files, postage stamp images, 
   * ''from Garching'': some detrend and difference images; 
   * '''MDS''' from Garching: detrend images
 * '''Edinburgh''' (see [http://pan-starrs.ifa.hawaii.edu/mailman/private/ps-ipp-users/msg00720.html Andy Taylor's message to ps-ipp-users] - list subscription required to see it)
   * We would encourage the suggestion that the MDS fields be sent in a "full" state, ie, clean and update does not have to be run, and they contain all data products.
   * To clarify what we think we need for KP11 is detrended, unwarped images (with warp information) for each exposure (ie unstacked) for the full field.
   * We need the full raw (flat-fielded, bias subtracted but nothing else) data for the full MDS fields, not postage stamps.
   * We need other IPP products such as the CMF file, star and galaxy catalogues.
 * '''Durham'''
 * '''CfA'''
   * Full catalogs.  50-100% of Medium Deep Survey; detrending images only.  Rapid-response postage stamp images.
 * '''JHU'''
   * Full catalogs, rapid-response postage stamp images all surveys. Access to sub-set MDS images (will work with CfA).
 * '''LCOGT/UCSB'''
 * '''NCU/TW''' 
  * Full catalogs;  Medium Deep Survey; detrending images only;  Rapid-response postage stamp images; cmf files.

= Postage-Stamp Server needs =

 * The Transient Classification Server requirements document specifies a worst-case of 100,000 request of 100x100 pixel stamps per day.
