Comments on LCs on this web page:

Period is close to correct. Limb darkening is small.

High air mass near end produced large rise feature. Nice OOT and ingress. Mid-transit time derived from ingress and adopted length.

7913OJ2

7913psx2

7913psx1

7911OJ2

Early, like all the others, but quite deep. Good to have a 7-hour session (helps establish air mass curvature coefficient).

Edwin Sheridan's first exoplanet light curve! Congratulations!

Almost perfect!

Early event, like the others; deeper depth than expected like other measurements.

Nice!

A little short on OOT baselines but good otherwise.

Out-of-Transit (OOT) Light Curves

Same dip at 06.1 UT. Must be a systematic.

OOT.

OOT.

OOT. Something systemtic going on.
