Dear Craig, ccd_r1 looks strange, one chip is saturated and the other is around 11000 (as before) Fabrice |

The problems with CCD1 are far beyond bad offsets. All four amps are railed at 64k. Lowering VBB did not change anything. There are plausible non-detector causes, but that is a matter for a different venue. I'll lower priority and leave this open for the offsets, which is blocked on the ics_config work. |

The current method of loading offsets uses image files headers, which seemed cute at the time. I'm moving them into ics_config files. |
