General Description

• This is a NACO SDI run using the laser guide star facility (LGSF) to observe
   the central regions of four quasar host galaxies. The quasar redshifts are selected
   so that one typical emission line can be detected in one of the SDI narrow-band
   filters. By later subtracting the off-line filter from the on-line filter, information
   about the morphology of emission line regions will be derived. For this kind of
   exploratory program, the expected flux levels are difficult to predict. A low flux
   level in the individual DITxNDIT images should not be surprising.
  
  Four independent and identical OBs are submitted for each of the four quasars. All
   quasars are observed with the LGSF. As indicated in the OB comments, the three brighter
   quasars should be observed with the LGSF and tip/tilt correction on the nucleus.
   The fainter source SDSS114203.40+005135.8 should be observed with the LGSF and tip/tilt
   correction on a nearby reference star which is marked in the finding chart.
  !!! PLEASE NOTE: As advised during phase II review, an alternative NGS has been
   included as second option in the .aocfg files for three of the sources (HE0354-550,
   HE1149-2103, SDSS114203.40+005135.8). In each case the original tip/tilt star is
   given as alternative NGS.
  
  Because SDI standard stars are not included in the standard calibration plan, each
   quasar is provided with a corresponding standard star (CAL_...). For each quasar
   the respective standard star should be observed *once* close in time to one of the
   four quasar OBs. The standard stars are observed in NGS mode with the standard star
   itself used as AO guide star.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• No critical constraints other than that given in the constraints set.

Time-Critical Aspects

• No time-critical aspects.

Special Execution Requirements

• Please try to observe the corresponding standard star OB (CAL...) *once*
   close in time to *one* of the respective four quasar OBs.

Special Calibration Information

• Photometric standard stars for the SDI are not included in the standard
   calibration plan. We have submitted OBs for one G2-type flux standard for each quasar,
   respectively. Per quasar the corresponding standard star should be observed *once*
   close in time to one of the four quasar OBs.
  
  In addition, we will require SDI flats as included in the standard calibration plan.
