Status of MegaPrime after the December 2002 Engineering Run

• Camera: working.
• Shutter: working - rare intermittent fault on the axis card
• Cryogenics: working.
• Filter jukebox: kept inactive before undergoing upgrades in mid-January
• Filters: only r' used
• Prime Focus Environment: stable. Likely to have a few light leaks as the jukebox is not tighten to the camera yet.
• CUTE and cabling: functional.
• Guiders/ISU: hardware working
• Guiding software: Guide stars acquired on each guider, and guiding done on one of the guiders with the ISU.
• TCS: mount model and instrument zero done. Very limited communication with MegaPrime Control already available.
• Session software: working, including archiving.
• Elixir and camera commissioning already done:
Zero point in r'
Noise check for the GFSU/FSA motors (OK!)
Mosaic geometry
Scattered light from nearby bright star (N/S done)
Darks on the telescope
Transfer curves on the telescope (no significant change with CEA data)
• Focal plane / WFC alignment: One focal plane tilt already done - will be further checked (though it seems to be a step in the right direction)
