General Description

• Definition SETUP: one normal setup contains 4 OBs: position star with
   dic1;
  position star with dic2; position fos4 with dic2; position fos4 with dic2.
  
  To obtain a systematic time coverage, a setup (group of OBs) should 
  executed roughly every month (indicated by the names Oct, Nov, etc.)
  The setups are identical and the separation should be about 1 month 
  to get equal time separation within this semester!
  Therefore there are 6 observations to be made in 6 months, with the 
  exception of March. Here, two observations are needed (best at a spacing 
  of about 2 weeks) to increase the density of the time coverage.
  In addition, two observations of the star only need to be executed 
  in October and December about 14 days after the execution of the full 
  observation setup of these months.
  
  This observing program is a direct continuation of earlier semesters
  programs 070.D-0607(A), 071.D-168(A),072.D-0524(A), 074.D-0141(A)
  and  077.D-0618. We are  monitoring  Eta Carinae continous changes
  of the spectrum and brightness. 
  
  We are obtaining one full spectrum of the star and observe a special 
  region (FOS4) within the nebula around Eta Car which shows the reflected 
  stellar spectrum.
  To peak up on the FOS4 position we are using an offset star north-east 
  of this position.
  
  A guide star and a finder chart for the guide star is given.
  The guide star's designation is U0300_10504917
  the position 10:45:12.898    -59:44:19.32   V about 12.1.

Special Execution Requirements

• Since we expect flux and line profiles to change with time, it is important
  that a full setup  - consisting of 4 OBs (Dic1 and Dic2 for star and FOS4) - 
  is taken at least within the same night, better right after each other.  
  We are planning to observe Eta Car during the whole ESO semester between
  October and April. At the beginning of this semester it will be harder to
  observe the object because it rises less high above horizon. Especially in
  October, November and December only a short time of the night (end of the
  night) are useful.  Due to these unusual observation times (in which the star
  is quite off from its culmination) we will accept higher than ususal air masses.
  
  The most important point for this monitoring program is the roughly equal time
  spacing between the observing setups (see definition of setup in the General 
  Description).  We like to have a set of spectra (one setup) every ~4 weeks 
  (e.g.  one month). This is indicated by the OB names, but it is not intended 
  to fix exactly the date of observation.  We just ask for reasonable time 
  intervals of about 4 weeks (e.g. NOT one spectrum taken on 31.Jan  and the next
   
  on 1.Feb...).  
  
  In March we need two observation setups, best spaced roughly by 2 weeks.  
  Two additinal observations on the star only need to be executed in October and 
   
  December, again about 14 days apart from the other observation in this month.
  
  Designation of OBs:
  
  position         month        dichroic
  ETA CAR FOS4    November        dic1          
  
  results in
  ETA CAR FOS4 NOV DIC1
  
  and in the same style:
  ETA CAR FOS4 NOV DIC2
  ETA CAR STAR NOV DIC1
  ETA CAR STAR NOV DIC2
  ...
  
  in March there are two setups of the same type:
  ETA CAR FOS4 MAR-1 DIC1
  ETA CAR FOS4 MAR-1 DIC2
  ...
  and 
  ETA CAR FOS4 MAR-2 DIC1
  ...
  
  The star-only observations (observed in Oct and Dec about 14 days 
  after the normal setups) are named:
  ETA CAR STAR14D OCT DIC1   
  ETA CAR STAR14D OCT DIC2   
  and
  ETA CAR STAR14D DEC DIC1   
  ETA CAR STAR14D DEC DIC2
