General Description

• By these observations we want to find binary stars among
  the hot horizontal branch of the Globular Cluster
  NGC6752. For this purpose we plan to obtain repeated
  observations of the same stars at different epochs.
  Because of this our observations are time-critical, and the temporal sequence
  for the OBs execution is reported in "Time-Critical Aspect" field.
  The observational constrains we can eccept for our OBs observation
  are reported in "Critical Observing Condition Constrains".
  
  Please, refer to the README file of the 079.D-0674(A) run for
  a full description of the observing strategy.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• We had the proposal approved with the following constrains:
  seeing <= 0.8, grey Moon, clear sky.
  But our program is time-critical (see "Time-Critical Aspect" field), 
  and we can accept a seeing<=1.2, full Moon, and variable sky
  transparency (thin cirrus) if this can help
  to observe out OBs according to the temporal sequence
  reported in "Time-Critical Aspect" field.

Time-Critical Aspects

• These observations cover about 3 months and are divided
  in 6 observing nights, i.e. 6 epochs (considering also runs
  079.D-0674(A) and 079.D-0674(B))
  A full description of the observing strategy is presented 
  in the README of the run 079.D-0674(A).
  
  The present run (079.D-0674(C)) is composed by two OBs (NGC6752_night6_A 
  and NGC6752_night6_B OBs) that should be possibly observed
  about ninety (90) nights after the reference epoch.
  
  In any case the sequence of the OBs is also indicated by the "User Priority"
  and the "User Comments" fields specified for each OB.
  
  We succesfully chacked the OBs for a HA range of +/-4 hr from the beginning of
  May to the end of September 2007.
