Prediction of Exoplanet Precisions using Information in Transit Analysis
Introduction
PEPITA is a Python package that allows making predictions for the precision of exoplanet parameters using transit light-curves. Behind scenes, it makes use of the Information Analysis techniques to predict the best precision you will get by fitting a light-curve without actually needing to perform the fit.
Motivation
Being able to predict the precision of parameters without needing to perform fits to data allows a more efficient planning of observations or re-observations. For example, if you find that an exoplanet of your interest which has been observed with a cadence of 1800s cadence will get an improved measurement of its radius ratio of 30% if reobserved with 120s cadence, you know that re-observations will be worth it. Or you may find out that the improvement is 1% and re-observing is not worth it.
