General Description

• This project carries out longslit spectroscopy of three quasar Narrow-Line
   Regions.
  The quasar PG0157+001 is part of this run B.
  
  The best observing period, taking into account the observing conditions
  and elevation, is 1th to 7th of august or 31th of august to 5th of september.
  
  Grism GRIS_300V+10 with filter GG375+30 is selected, yielding a wavelength coverage
   of
  3850-8650 A with a dispersion of 11.2 nm/mm. With a redshift of 0.163, we will obtain
   emission lines from [OII] 3727 A to [SII] 6731 A.
  
  The total integration time will be split into several exposures to match the one
   hour OB length and to improve cosmic ray rejection. One additional short exposure
   of 180 sec will be taken.
  
  A slit width of 0.7 arcsec is chosen. The slit shall be centered on the bright nucleus.

Waiver Requests

Critical Observing Condition Constraints

• Sky transparency: Clear
  Seeing: better than 0.8 arcsec
  Airmass: less than 1.5
  Lunar illumination: 0.1, dark time
  Minimum moon angular distance: 70 degree, dark time

Time-Critical Aspects

• none

Special Execution Requirements

• If possible, please carry out the OBs directly after one another. 
  
  Please center on the bright nucleus.
  
  We defined a special OB for a standard star (LTT9491) which will be used to correct
   the telluric absorption lines. 
  Thus, we used the same slit width as our scientific objects, but one observation
   is enough.
  Please try to observe this object at a similar airmass as our scientific objects
   and close by in time of one of the two scientific OBs.

Special Calibration Information

• If possible, please use the standard star LTT9491 or Feige110 as normal
   spectrophotometric standard star.
  
  Standard calibration is required.
