General Description

• The Targets
  --------------
  The targets are late M dwarfs and early-mid L dwarfs, for which we want radial velocity
   measurements (at the 1-2km/s level). They are high proper motion sources, so the
   coordinates have been corrected to epoch 2008.6. These coordinates should be accurate
   to better than an arcsecond. The targets are faint (I=15-17), but previous observations
   have shown that offset stars are unnecessary. Our observations are designed to yield
   SNR of ~15, to facilitate our cross correlation.
  
  Radial velocity standards
  ------------------------------
  Two of our targets (VB10 and GI876) are radial velocity standards. These can be
   executed at any time in the program
  
  Acquisition
  -------------
  Finders (from SuperCOSMOS) are available. They are I-band, and are 2x2. In each
   finder the target is boxed.  There are often multiple sources around the target
   position, however the finder should make it clear which one is the target.
  
  Telluric standards
  ---------------------
  The bright Telluric standards were chosen so that they will be executed at approximatley
   the same airmass as the target.  There is one for each science target and radial
   velocity standard. The I band brightness of these tellurics is given in the OBs
  Details of when the tellurics should be taken can be found in the special execution
   requirements section.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• The observations do not require a specific lunar phase, they can be observed
   in bright time. To obtain the desired SNR for our targets we require <1" seeing.
    THN transparancy is suitable for our program.

Time-Critical Aspects

• The Position of these objects makes them most suitable for observation
   in August.

Special Execution Requirements

• For each of the science targets and radial velocity standards there is
   a telluric standard associated with it.  The science targets and their associated
   tellurics should be observed in pairs.  The tellurics will either need to be executed
   before or after the science/RV standard frame.  When they are to be observed can
   be found in the title of the tellurics observation block.

Special Calibration Information

• We have included a telluric standard for all science observations.
