+[[PageOutline]]
+
+Summary page of information for the MD GR0 (grand reprocessing version 0) including the new reference stack in the V3 tessellation with the start of new observations of MD10 in OC142. This is version 0 as the test start of full reprocessing of the MD fields to be balanced along with 3PI stacks and nightly science, generation of new reference stacks and not yet including a revised reference catalog (MD10, 01, 02).
+
+
+= MD.V3 Tessellation =
+
+The new V3 tessellations are defined at [wiki:PS1_Tessellations] with the following properties:
+
+* 0.25"/pix (previously 0.2"/pix up through V2, and from natural ~0.258"/pixel)
+
+* 10 x 10 skycell grid (previously 12 x 12)
+
+* revised centers if necessary -- was necessary for MD10 (will also be for MD04
+
+* +x is West (flipped from before +x was East), +y is still North
+
+* 320 pixel (80") overlap (from 300 pixels, 60", in V2) 
+
+
+
+
+= MD10.GR0 =
+
+Started for OC142 (July 15, 2011). Initial reprocessing version.
+
+* z,y-band data processed prior to full Dark model improvements (higher background makes effect insignificant). gri-band processed after Dark model improvements.
+
+* same photometry reference catalog same as before 
+
+* ...
+
+* stack-stack diffims still using forced convolution of reference stack to input images
+
+* ...
+
+Data_group names:
+
+
+== MD10.V3 reference stack ==
+
+|| version || FWHM (major) || 
+
+* FWHM mean,histograms vs V2
+
+* Mask fractions vs V2
+
+* photometry vs V2
+
+* reference stack vs typical nightly stack skycell comparison
+
+
+== Distribution ==
+
+* ps1-md-GR (full): warp, nightly stack, warp-stack and stack-stack diffims
+
+* ps1-md-GR-cat (cleaned): camera, warp-stack and stack-stack diffims
+
+'''NOTE: full chip and camera products will not be included as datastore release bundles unless there is interest'''
+
+Cleanup time-scale TBD see below
+
+Data bundles will unpack in the following ways
+warp-stack diffims: all under gpc1/MD10.GR0/2011/08/09/MD!0.V3/skycell.NNN -- very large directory
