Abstract for MTS:
Notes on acq strategy:
----------------------
During the execution of OB 302653 the observer aborted the OB and started it
again skipping half of the acq sequence. Since there is a second OB identical to it
I have been in contact with the PI on this issue. The acq strategy for this OB,
and for some of the other OBs also, is this
(1) place ref object on slit, with slit PA such that both ref and target are
on the slit.
(2) perform offset. This offset does not move the target off the slit as the
observer reported. This offset moves the target along the slit
to a pre-decided position.
The team has looked at the data that were taken and has confirmed that the
acq sequence is correct. I have therefore placed the OBs in question back
into the queue. Please execute the OBs exactly as they are, including offsets.

original comment:
---------------------------------
Another redshift run of the GRB host large programme. Due to the loss of red
sensitivity of FORs1 after the upgrade, this run was moved to FORS2.
