Pipeline usage at ING

• Quicklook Pipeline reduction
  During the night the observed frames are automatically quicklook reduced (steps 1-4 of the pipeline). The files are available to the observer about 5 minutes after a frame was taken. Files can be accessed in IRAF by prepending qldata$ to the file name and replacing "r" by "q" in the file name.
  r123456.fit -> qldata$q123456.fit
  Quick look reduced data is only kept until the beginning of the next observing night.
• Science pipeline data reduction
  At the end of each run the quality of calibration frames is assessed and the best bias and flat field frames built. All data is then processed through steps 1-4. Steps 5-7 will be added soon. The reduced data will be available about 3-5 days after the observing run ends.
