RAW data calibrated and reduced using AstroImageJ, including information on AIRMASS and additional (optional) detrending parameters for AIRMASS. Tried many different combinations of comps but could not match the expected transit depth for ExoClock. However, the transit depth obtained is consistent with observations from others on Exoplanet Watch for the R filter.
