General Description

Spectroscopy to determine the orbital period of up to five red dwarf -
 white dwarf systems selected on their colours in the Sloan Digital Sky Survey, as
 well as the VLT pre-imaging done in 081.D-0753(A). Set-up is to use the 1200 holographic
 grating with (3x300s) integration times within one OB. Each source has 6 OBs associated
 with it, labeled SDSSXXXX-YY_01 through ...YY_06, where XXXX-YY are the short-form
 coordinates of the source. 

Phase 2 observations are submitted as the A-run imaging is verified. 

Please note carefully the observing order: 
- Spec_SDSSXXXX-YY_01 is the first OB to be executed on source SDSSXXXX-YY. 

The following OBs need to be executed according to the following time scheme:
-Spec_SDSSXXXX-YY_02: 4 hours after Spec_SDSSXXXX-YY_01
-Spec_SDSSXXXX-YY_03: 1 day   after Spec_SDSSXXXX-YY_01
-Spec_SDSSXXXX-YY_04: 2 days  after Spec_SDSSXXXX-YY_01
-Spec_SDSSXXXX-YY_05: 3 days  after Spec_SDSSXXXX-YY_01
-Spec_SDSSXXXX-YY_06: 4 days  after Spec_SDSSXXXX-YY_01
