Slew rotator by 180 degrees from Sky PA 120 run019 run020 Acquisition run021 PR shot run022 PR shot run023 PR shot run024 Acquisition - problem with usdriver orientation run025 Acquisition - problem with usdriver orientation run026 Acquisition run027 Science data - WD primary eclipse covered, but tracking lost during BS egress run028 Acquisition - wrong rotator angle run029 Science data - can't find the AM CVn star! run030 SDSS standard - u' throughput test. Good data (not acquisition) run031 Junk - wrong filter run032 SDSS standard - g' throughput test run033 SDSS standard - r' throughput test run034 SDSS standard - i' throughput test run035 SDSS standard - z' throughput test run036 Acquisition run037 SDSS standard - u' throughput test run038 Junk - saturated run039 Junk - saturated run040 SDSS standard - g' throughput test run041 SDSS standard - r' throughput test run042 SDSS standard - i' throughput test run043 SDSS standard - z' throughput test run044 Acquisition run045 Acquisition run046 Acquisition run047 Acquisition run048 Acquisition run049 Science data - nice primary eclipse. Photometric. Seeing ~1.5" run050 Testing Stu's usfinder - looks like TNO TCS defines sky PA from N through W, not E! run051 Open cluster. r' band data for Stu to test vignetting run052 Open cluster. Testing vignetting by stepping telescope. This is the zero position run053 Step telescope 20" South run054 Step telescope 20" South (40" accumulated) run055 Step telescope 20" South (60" accumulated) run056 Step telescope 20" South (80" accumulated) run057 Step telescope 20" South (100" accumulated) run058 Step telescope 20" South (120" accumulated) run059 Step telescope 20" South (140" accumulated) run060 Rotator Limit run061 Rotator Limit run062 Rotator Limit run063 Rotator Limit run064 Rotator Limit run065 Rotator Limit run066 Rotator Limit run067 Step telescope 20" South (160" accumulated) run068 Step telescope 20" South (180" accumulated) run069 Step telescope 20" South (200" accumulated) run070 Step telescope 20" South (220" accumulated) run071 Step telescope 20" South (240" accumulated) run072 Step telescope 20" South (260" accumulated) run073 Step telescope 20" South (280" accumulated) run074 Step telescope 20" South (300" accumulated) run075 Step telescope 20" South (320" accumulated) run076 Step telescope 20" South (340" accumulated) run077 Step telescope 20" South (360" accumulated) run078 Step telescope 20" South (380" accumulated) run079 Step telescope 20" South (400" accumulated) run080 Step telescope 20" South (420" accumulated) run081 Step telescope 20" South (440" accumulated) run082 Step telescope 20" South (460" accumulated) run083 Step telescope 20" South (480" accumulated) run084 Drift mode testing run085 Drift mode testing run086 Drift mode testing run087 Drift mode testing run088 Drift mode testing run089 Drift mode testing run090 Drift mode testing run091 not a good bias - stars in field run092 slide not in far enough run093 bias - slide in beam, but people in scope so maybe dodgy run094 Acquisition run095 Elme's new AM CVn system (CSS090331:084414-012807). Photometric, seeing ~1.5" run096 Acquisition run097 Lovely primary eclipse, photometric, seeing ~1.3" during eclipse. run098 Acquisition run099 PR shot. Comet moves obviously. run100 Blank field with stars; offset from previous object still in place. run101 Moved to avoid stars. Telescope spiralled. Central blob obvious run102 Last frame or two saturated. Very odd moving wave structure run103 Waves here too. They rotate when rotator rotates! run104 They don't seem to so much here though. Saturated last frames. run105 Horrible structure in the u. Suddenly saturates at end run106 Another shot at it to see if saturated values can be cleared. No they can't. End of night. Good weather; some oddities in the data need investigation.
