General Description

Radial velocity measurements of 6 low-mass spectroscopic binaries in the
 ONC region.

There are two type of OBs:

g1_u1 and g1_u2 - Giraffe targets are the same in both groups, only UVES targets
 change. So please do not execute more than one OB of this program per night. 

The guide star chosen is close the lower magnitude limit of R=13. If needed the
 night astronomer can use one of the other 2 potential GSs given in the .ins file
 with the guide probe position set to "NEG"

Waiver Requests

An waiver (waiver ID:076.C-0524A.01) was requested to have OBs longer
 than 1hr.

Critical Observing Condition Constraints

Special Execution Requirements

Please, do not execute more than one OB of *this program* per night.

Since all OBs (ONC_g1_u1 or ONC_g1_u2) have the same giraffe targets, executing
 an ONC_g1_u1 and an ONC_g1_u2 at the same night *is not* allowed either (this means
 that I'll have more than one radial velocities point almost at the same orbital
 phase!).
