Changeset 21211 for branches/pap_branch_20090128/psModules/src/camera/pmHDU.h

Timestamp:

Jan 28, 2009, 2:33:51 PM (17 years ago)

Author:

Paul Price

Message:

Changing pmReadout.weight to variance. Adding pmReadout.covariance which will carry around a covariance pseudo-matrix, allowing us to calculate the pixel-to-pixel variance. pmReadout.covariance now exists and is set, but no mechanism yet to read/write, or use it.
