Special Remarks:
Highly time critical
Abstract for MTS:
UVES observations of two unresolved detached eclipsing binaries in NGC6791.
Requirements: a lot!
1. time intervals when to observe the OBs
2. airmass should never be worse than 2.3 - bear in mind that target has DEC=+37!
Notes: OBs are 1.5h long. Each OB has 2 ThAr attached, bracketing the science
exposure (with a dummy science exp before the first ThAr_att). In a night when both Targets are observable, NGC6791_6840 has the highest priority.
(ADDED on 20.06.2008) In the "time-critical" section the PI has provided a table which contains the date that each OB has to be executed in order to avoid phase repetition. The column "PHASE" gives the last digit of the OB name. For instance, the OB NGC6791_6840_3 can be executed in one of the following dates June 30, July 17, Aug 21, Sep7 and Sep 8.
For the NGC6791_12390 OBs, the users does a small offset along the slit after the dummy exposure in order to better center both stars (see FC) in the slit.
(ADDED ON 17.07.08). PI changed the OB NGC6791_12390_10 to observe only the faintest star (as indicated in the finding chart) in ELEV mode. For the other NGC6791_12389_* OBs, both stars are put in the slit (see readme file and FC).
(ADDED ON 31.07.08). PI changed the observing dates for the remaining OBs and added another epoch for 6840.
(ADDED ON 02.09.08). PI added observing dates for the remaining OBs until the end of the period.
