We present the comparative study of the physical and orbital parameters derived for the extra-solar planetary systems using these two codes. For our analysis, we have taken the two transit data of the different extra-solar planetary systems observed by us, as well as a few available in the literature. To estimates the above said parameters, we modeled each light curve by applying the same process using these two codes. We found that the estimated parameters obtained from these codes shows good agreement. However, the errors estimated by JKTEBOP code are smaller than those reported by TAP, which justifies the result of Hoyer et al. (2012) and Turner et al. (2013) that JKTEBOP underestimated the errors. |
