General Description

This program is designed to continue a radial velocity survey for binaries
 within the young massive galactic cluster Wd1.

The initial phase of observations were obtained in 2008 and were designed to search
 for short period binaries, while this extention is designed to search for systems
 with orbital periods of months to years.

Consequently we request that this run  383.D-0633(A) be executed in the first half
 (Aril-June) of the semester, with the second 383.D-0633(B) executed in the second
 half (July-Sept), ideally  with 3 or more months separating them in order to optimise
 the length of the observational baseline. 

This constraint reflects the `Time Intervals' selected in each of the OBs for both
 runs. 

However, if this is not possible due to adverse weather/instrumental problems/scheduling
 constraints we request that these conditions be relaxed such that both runs are
 executed. In this respect if it is not possible to execute  383.D-0633(A) in the
 first half of the semester then please attempt it in the second half as well as
 83.D-0633(B). Likewise, please ignore our contraint that both runs be executed 3months
 appart if this would preclude both runs being executed.

Critical Observing Condition Constraints

```
See General Description

Time-Critical Aspects

See general description.  Also note that each of the four OBs within run
 A and Run B are entirely independent of the others within that particular run (each
 OB has a different set of targets) and so don't need to be carried out within a
 certain timeframe with respect to the others.  However we would *ideally* require
 the 3 month separation between carying out the *same* OB in run A and run B.
