Detailed doppler measurements show that Pratham is object 41791, 2016-059J.
This is based on the most recent TLE sets, that were published by the JSpOC. Unfortunately the collection of TLE sets for the PSLV-C35 launch is not stable yet. The JSpOC continues to cross-tag TLE sets and to make major changes to some of the TLE sets. So some further changes may be expected in the coming days.
The JSpOC has not yet identified any of the objects from the PSLV-C35 launch. It seems quite obvious however that ScatSat is object 41790, 2016-059H.
