Target RA (J2000): 197.317459 and deg Target Dec (J2000): -60.30836 and deg Gaia GMag: 8.09 Programme ID: CH_PR100017 Programme Manager: PAGANO PI of observing programme: Benz Title of programme: ANCILLARY SCIENCE - Recovering ephemeris Abstract: There are a number (about 2 tens) of transiting planetst of interest for follow-up characterizing measurements (JWST E-ELT) whose ephemeris must be recovered before going with large facilities and this can be done by CHEOPS. It is proposed to monitor one transit per target the observing window centered on the transit time predicted by the best available ephemeris and lasting two times the uncertainty on T0 plus the transit duration. Target list and target priority shall be modified according to results from K2 and TESS campaigns. [truncated! Please see actual data for full text]
