Observational settings/limits
- original criteria to observe Ton 599
we request 50 hours of observations unless the average integral photon flux (>100 MeV) goes down below 0.5×10−6 cm−2 s−1
It seems the gamma-ray spectrum of Ton 599 is sometimes hard (<2.0) (especially since April) and variable. So we want to request to schedule short exposure observations (1-1.5 hour) as a monitoring purpose rather than longer exposure when this source can be scheduled (=no collision with other higher priority sources).
