Estimated Total Execution Time (hours, including overheads)

• 6.9

General Description

• The idea of the project is to gather 10 EMMI spectra with grating #3 of
   two candidate Wolf-Rayet binary systems (one has m_V=9.3, the other m_V=12.3) in
   order to find out whether they are long-period binary systems and establish their
   orbital solutions. To sample various time scales, the observations should ideally
   be spread over the entire period 77 with a more intensive coverage in August and
   the remaining observations roughly separated by at least a few weeks. I have prepared
   ten OBs for each target. Following the schedule for service mode runs at the NTT,
   I have specified time windows in accordance with the above strategy. 
  
  Note that both targets need not be observed on the same nights.

Time-Critical Aspects

• As stated above the observations should be spread over the entire duration
  of period 77 with a more intensive campaign in August. 
  Therefore, the ten OBs have the following time windows:
  wr63_obs1 and wr69_obs1: May 1 - May 15
  wr63_obs2 and wr69_obs2: May 15 - May 31
  wr63_obs3 and wr69_obs3: June 1 - June 30
  wr63_obs4 and wr69_obs4: July 1 - July 31
  wr63_obs5 and wr69_obs5: July 20 - August 5
  wr63_obs6 and wr69_obs6: August 3 - August 10
  wr63_obs7 and wr69_obs7: August 7 - August 15
  wr63_obs8 and wr69_obs8: August 10 - August 20 
  wr63_obs9 and wr69_obs9: August 19 - August 31
  wr63_obs10 and wr69_obs10: September 1 - September 30
  
  Note that both targets need not be observed on the same nights and that two
  observations of the same target should NOT be done during the same night.
