Special Remarks:
Best chance to complete run in P76 is dark/grey SM time in October! Check updated MTS!
Abstract for MTS:
Single target programme : faint QSO (R = 19.5) at z=2.572, the same one from
P74, that did not get observed. All remaining OBs are identical, all using Dic1 390+564, and all having 5320s integrations.
QSO should be visible at acquisition (but see ExecNotes below made by Cedric Ledoux). If not, check README for info on possible offset star, or let us know and PI will be contacted again.
Note that on October 4, after comments received by PSO (see USD-14499), PI revised
obs.strategy: he changed the exposure times from 3200s to 5320s (the remaining OBs
are thus 9 and not 14) and selected a seeing constraint =0.8", which was indeed what
the programme had requested at Phase1 and for which it had been scheduled. This is not
the 0.7" or better seeing suggected by Cedric, but it slightly improves on the previous value.
Execution Notes (04.10.05 - from Cedric): target is very faint - need to integrate 120s in the slitviewers. With slit width = 0.8", a seeing=0.7" or better would have helped a lot. So, try to execute OBs under good seeing conditions.
Notes from USD: since there will practically be not much dark/grey time in
November, and target is already set in December, next few nights in October are
the best chance to complete this programme in P76.
