General Description

• This programme aims to detect or constrain the Lyman continuum flux from
   Lyman break gakaxies at redshift about 3. The fluxes are very very faint because
   of the high opacity of the ISM and the IGM. Thus, most of targets will not be detected.
   Therefore, we have to keep the background noize as low as possible. The observing
   wavelength is around the OII emission line, namely 3727 A. The current best limiting
   magnitude at the wavelength is 27.3 mag(AB)/arcsec2 (3-sigma) which was performed
   by us with the VLT/FORS1. We should reach at least this limit. On the other hand,
   we need not to resolve the targets.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• The most important point for this programme is to reduce the background
   noize. 
  Dark nights are absolutely essential since the observing wavelength is around 3727
   A.
  Photometric condition is also important, but Clear condition may be acceptable if
   it is unlikely to suffer clouds passing.
  Seeing condition has less priority.

Time-Critical Aspects

• None.

Special Execution Requirements

• None.

Special Calibration Information

• According to the FORS manual, only one standard star given by the 
  calibration plan will be taken after our scientific OBs 
  in a photometric night. To determin the airmass dependence accurately, 
  we need several standard stars taken in different airmass conditions.
  Thus, we request to take other two standard stars BEFORE A SET OF  
  our scientific OBs for photometric nights. We only request to take 
  these standard stars for TWO photometric nights. It means that 
  if our photometric OBs are executed in three different nights, 
  we do not request to take the additional standard stars
  in the third night.
  
  We submit the following two standard stars: 
  LTT 377, spectral type F, magnitude at the observing wavelength about 12.3 mag
  LTT 1020, spectral type G, magnitude at the observing wavelength about 12.5 mag
