2. Quick Reference for Observers

2.1. Data Reduction

See this page for documentation on the data reduction pipeline.

2.2. Data Format & Fields of View

Both cameras produce 2048 pixel square images. The field-of-view of the IFU camera is roughly 30” on a side, while the Rainbow Camera (RC) has a field-of-view that is roughly 13’ on a side that is divided into quadrants for each of the four filters (ugri), which have individual FOVs of about 6.5’ on a side.

2.3. Exposure Time Estimates

IFU exposure time recommendations for standard stars (single A exposure):

  • 10 - 11 mag –> 120s
  • 11 - 12 mag –> 240s
  • 12 - 13 mag –> 360s
  • 13 - 14 mag –> 500s

Exposures longer than this might be considered for an A/B pair.

IFU exposure time (total) recommendations for science targets (split A/B pair):

  • 15 mag –> 420s
  • 16 mag –> 600s
  • 17 mag –> 900s
  • 18 mag –> 1800s
  • 19 mag –> 2700s
  • 20 mag –> 3600s
  • 21 mag –> 5400s
