I mentioned in my recent post on astronomy and astrophysicists that I consider myself an astronomer because of the emphasis I place on observations and data in my studies. While working on a large survey, it’s not surprising that data would have such a large focus for me. It seems only fair to share the awesomeness and fun of working with all this data. This post will be a general timeline for the data processing, and follow-up posts will go into more details for each step.
Day 0: The data is observed at Arecibo.
Day 1: The data is transferred from Arecibo to Cornell. The initial calibrations are done.
Day N (): The data is flagged to mark all the radio frequency interference (RFI).
Day X (): The data is ‘gridded’ – three-dimensional cubes are produced and source extraction begins.
Day Y (): Source extraction is complete for a strip of sky and the source catalog is officially published.
