General Description

• This is a program to do high resolution spectroscopy of 5 stars that were
  found to be transited by giant planets. Four of these are very faint targets (I=14-16),
  discovered by the OGLE survey. The last one (TrEs-1) is brighter (V=11.8). 
  The general scientific goals are:
  
  - Derive precise stellar parameters and chemical abundances for the stars (including
   Li)
  - Derive a chromospheric activity index based on CaII H and K lines near 3900A
  
  To achieve this goal, we are using:
  
  - Red arm: slit of 0.9'' and bin 2x2 for OGLE candidates and 0.9''/1x1 for TrEs-1;
    This should provide us with a R near 50000 for the spectra.
  - Blue arm: slit of 1.1'' and bin 2x2 for all targets; This should provide us with
   R>40000.
  
  Different priorities were given to the different targets. The goal of
  our priority scale is such that we prefer to have one priority 1 object with
  all OBs observed before you start observing OBs for a priority 2 object.
  
  Different OBs of the same target are named: *A to *F. No difference exist between
  these OBs.

Waiver Requests

• We have asked to add OGLE-TR-10 to the target list. Granted.

Critical Observing Condition Constraints

• OGLE candidates: faint targets (I=14-16): dark time is needed. Also, if
   choice
  is possible, please try to observe under good seeing conditions (the critical
  seeing limit has been lowered because the proposal is in priority B).
  
  For TrEs-1, no dark time is needed (V=11). However, this star is observable
  at a high air-mass. In this case, please be sure that no thin cirrus exist 
  IF moon is bright.
