Hi Roger
I did try another example, and had much better results:
Using this lightcurve i estimated the exoplanet radius in the usual way:
The result I obtained was
Not too bad since the accepted value is 1.079 ± 0.033. The difference could be just trying to estimate D from the laptop screen.
I’ve been checking coordinates using SIMBAD.
Whether this is because the data is better or because I’m getting better at using HOPS I’m not sure.
Best regards
Gordon
