Please be aware that the RCT’s online Exposure Time Calculate has been modified to fix a bug in calculating the signal-to-noise for a known magnitude and integration time. Calculations modes for exposure time and magnitude are unaffected.
It looks as if we were slightly off in our pointing for some observations last night resulting in acquire errors for some guided targets. Observers who did obtain data, can you let me know if you also saw a slight offset in your pointing. Any other comments about data quality you’d like to add?
