after some thinking I decided to change the way how we charge for two special situations of imaging reuqests. This has become necessary as some observations occupy alot of telescope time, but effectively consume very little imaging time ending up in low charges. Basically this happens in two situations:
- Imaging plans with very short (< 1 minute) exposure time per frame
- Imaging plans with RBI preflashing
In the first case, between slewing, guiding and postprocessing, it takes about three minutes for a single frame of for example 30 seconds.
In the second case, RBI preflashing takes about 2 minutes of additional time.
We are now charging an additional 1 points per RBI observation, and 0.5 points for short observations. Let me know if I should change anything here. I hope this improves fairness towards all users.
