Transit light curves



Same transit as the one below, but different filter.




OOT is well-behaved; good choice of refernce stars.


Good first submission. Need more OOT, but solution agrees with expection very well.


Nice.




Observer is Isaac Cruz (Ohio), using a clear filter (disregard the axis label). Mid-transit was early (~4 min).


The model fit treats this data as an ingress only for timing purposes.




Something funny happened near end of obs'g session; otherwise, good fit.


Beautiful!


Note: I include partial transits for the purpose of searching for anomlaies after egress (or before ingress) that could be produced by forward scattering by a hot Jupiter's ring system or dust cloud. The above Summary Table does not include transit measurements from partial transits.

Out-of-Transit (OOT)


Out of transit observation, after a false start requiring re-acquisition with different flat frame-related offset.
