Hi Group,

I'm observing an eclipse for a known exoplanet and are having difficulties with detrending when meridian flip occurs in the middle of eclipse or just at the time of ingress or egress because I don't know how to do a model fit for an eclipse.

Without a model fit the light curve will not continue at the same level of flux after meridian flip even when using 'Meridian flip' detrending parameter. I'm using left and right markers for data normalization to leave out the eclipse part.

What is the proper way of handling this situation?

My final purpose is to get as many eclipse observations (whole or partial) measured by AIJ and then take all data files into IDL for further analysis.
