Comments on LCs on this web page

     The period for TrES-1 apears to be accurate. Transit depth and length also seem to be well-established. No anomalies yet.
       Eventually all transit parameter measurements should have SE uncertainties.

Basic Data

    RA = 19:04:09.8, Decl = +36:37:57
    Season = July 09
    B=12.607, V = 11.764, Rc=11.300, Ic = 11.362, J = 10.294, K = 9.819, B-V = 0.843 (BVRcIc from Henden)
    HJDo = 3898.87342
    P = 3.0300737 day (from Narita et al, 2007)
    Depth = 25.5 mmag (R-band)

Transit Light Curves



Only useful for pre-ingress anomaly search.





Good choice of reference stars (no trend or air mass curvature).


Right on time, and a little deeper with CLR than R-band.


Nice having a V-band LC (after 3 yrs).


Cindy Foote's "gold standard" (when she uses the 24-inch) shows excellent agreement with the ephemeris mid-transit time and also transit depth.


The computer clock must have been off 1 hour, so mid-transit occured ~1 minute late, +/- a few minutes. Length is uncertain because ingress was missed. Good depth agreement.


Excellent agreement with expectaion for mid-transit time, length and depth. First submitted data by Ramon Naves.


Good agreement in all respects.


Good job.


Beware the high air mass at the beginning. Nevertheless, the depth agrees with a later concensus.


Marginally useful (one of the first LCs).


Marginally useful (one of the first LCs).


Marginally useful (one of the first LCs).


This is one of the TrES-1 LCs that led to interest in the possibility of a brightening after egress.


Beautiful! One of the first, if not THE first, amateur LCs of TrES-1.
