  1. Function to get the mosaic points giving a central pointing. Should taking in a ac.ICRS, and return a list of ac.ICRS,
def compute_mosaic_pointings(central_pointing: ac.ICRS) -> List[ac.ICRS]:
  ...
  1. Ensure the full mosaic fits within TRECS. I.e. take central pointing as central of TRECS, then get all the mosaic pointings, and then makes sure 3x3 patch around each mosaic pointing fits within TRECS. Best would be to demonstrate this with a plot of the mosaic pointings, and a 1.5deg radius circle around each point. Note, take into account projection effects when drawing the circles.

  2. Verify with group what dish effects parameters we will need to use for each manufacturer.

  3. Get source count distribution for >1Jy sources in FIRST, and sample over the entire sky, create new component list, assuming unresolved point sources. We'll likely repoint TRECS around the sky, but keep these bright sources fixed for consistency between runs.
