General Description

• These observations are part of a project to study the stellar galactic
   bulge kinematics in several 
   low-foreground extinction windows. Our data consists on Proper motions by WFPC2-ACS
   and the radial velocity counterpart by VIMOS-IFU. Our goal is to constrain the bulge
   kinematics as far as possible using 
   the 3-D kinematic information combined of both types of data.

Waiver Requests

• A extension of second phase was granted for these observations. The reason
   is the photometric-proper motions  counterpart of this P79 programme, which was
   affected by the failure of ACS. Additional time was necessary to  evaluate the previous
   data and to obtain an answer about our proper motion observations from STsci.  In
    order to optimize our observations (and scientific goals), we have re located some
   of the pointings. 
   Pointings in fields with proper motions already calculated and without spectroscopic
   observations from
   previous observations (P71 and P77) were preferred.

Critical Observing Condition Constraints

• In the case of bulge fields and darkbulge fields we require 0.8 of seeing
   and thin cirrus. Standard stars  fields just require seeing 2.0 and thick cirrus
   as already mentioned in every OB.

Time-Critical Aspects

• none

Special Execution Requirements

• Since the main use of this spectroscopy by VIMOS-IFU will be radial velocities,
   we would prefer to have velocity standard stars observed as close as possible to
   our target fields, where that should be no more than 1 day; therefore the same standard
   observation can be used for two consecutive  days. Using a standard star of several
   days apart (2 or more) increases the error in the correlation which calculates the
   final radial velocity. Consequently, we have indicated with priority user number
   2 for the velocity standard star (and darkbulge fields), and 3 for some of our fields.
   Similarly, regular darkbulge observations (used for sky-substraction) would be necessary.
