• 2013-04-19 CSPad CxiDs1 alignment
  Local: ~dubrovin/LCLS/CSPadAlignment-v01/calib-cxi-ds1-2013-04-19/*/0-end.data
  center and tilt types are available after optical alignment of quads.
  need image with data for quads alignment in the detector.
  not deployed.

2013-01-24   xppcom13 - had problems with electronics. Is fixed on 2013-01-29:
2013-01-29   xppcom13 (when tested, should be copied for xppi0113, xppi0213, xppi0313, xpp66213, xpp66613, xpp67713) 
             xcs72913 - detector borrowed from xpp
