Abstract
“We present a study of the exoplanetary systems KELT-1 and WASP-
33, observed with the San Pedro Mártir 84cm telescope, using the transit
method. We carried out image correction and data reduction of both systems
by modifying and using the aperture photometry software defot, a point-and-
click IDL tool. Moreover, we performed several tests changing the values
of several data reduction parameters in order to check the robustness of the
software. We noticed that small variations in the values of these parameters
do not affect the light curves significantly. We report light curves of KELT-1
in the R and V filters, and light curves ofWASP-33 in the U filter. Concerning
KELT-1, we performed the light curve fitting using the Transit Analysis
Package (TAP), an IDL software that allows to choose fit parameters setting
limits and initial values. We also performed many fits using curves of different
filters and paying particular attention to curves presenting a residual trend
after the airmass correction. In our fits we obtained results consistent with
the reported values, as well as values for the planet/star radius ratio Rp/R*
for KELT-1b in the R and V filters, which have not been reported before.”
