Date: Fri, 22 Jul 2005 01:30:31 -0600 From: Dan Long Subject: Imager Calibrations 20050721 (MJD 53573) Imager Calibrations for 53573 Got Linearity data on g4 and g5. g4 linearity set is broken in two parts due to ptvme failure after 5 frames, then a stageX position error. Found error in recovery procedure when one gets kicked out of IOP due to ptvme problems. The dewar argument in getIllumCol needs to be the stageX position for the desired dewar rather than the dewar number itself. g4 linearity.

The number 4 is rather suspiciously the same as the dewar number in this case... im> set iccd 4 im> set color g im> set msprow [getrow $color] im> set monotst Linearity im> getIllumCol 4 linear_g_partial.list A little poking around solved the mystery. The second argument of getIllumCol is the stageX for the desired dewar _not_ the dewar number itself. So the g5 completed without incident.
