General Description

The goal of this run is to determine the accurate orbital period of a
 cataclysmic binary, SDSS J013701-091235.  We use radial velocity curves of H_beta
 and other Balmer lines.  The orbital period is roughly estimated to be 1.4 hours.
  We prepare 7 OBs for this goal (J0137LSS-*).  Each OB has same configurations of
 equipment and covers ~55% of an orbital cycle.  We don't require continuous runs
 for these 7 OBs.  In order to accurately determine the orbital period, a longer
 baseline of the observations is more preferable.  We prefer to perform these 7 OBs
 for several months rather than continuous 3 nights.  The other 2 OBs are for low-resolution
 spectroscopy; one is for the target (J0137LSS-red_snap) and the other is for its
 spectrophotometric standard star (CAL_redspec_G158-100LSS).  These 2 OBs should,
 hence, be taken at the same night.

Special Calibration Information

There are 2 OBs which are for low-resolution spectroscopy; one is for
 the target (J0137LSS-red_snap) and the other is for its spectrophotometric standard
 star (CAL_redspec_G158-100LSS).  These 2 OBs should, hence, be taken at the same
 night.
