We did Segue/Boss photometry. The next plates are finished: 2640 (baoTest), 3149 (segue), and 3150 (segue). Obtained useful signal on plates 3134, 3122, 3154. For Connie: We obtained some signal on segue plate 3134 (cart3). The total sum is 151.4. We ask Connie to check is this plate finished and can be unplugged for Marvels run or do we need to keep it for next Segue observations. ---=== OBSERVING LOG ===--- Afternoon: --------- Spectro focus was not changed. It should be set for an air temp of 0 to -1 C. No problems noted during afternoon checkout Data for MJD 54769 removed from disk.
