General Description

• This is an imaging run of the debris disk star HD25457 in the N and Q
   bands with Sic and Q2 filters. The finding chart shows a K-band (2 MASS) FOV where
   to find our science objects.
  
  - Science HD25457 N~1 Jy and Q~0.2 Jy (Lower limit so far). 
  - Calibrator HD31767 is N~9.1 Jy and Q~3.7 Jy (NOT Part of the CP)
  - Calibrator HD34055 is N~29 Jy and Q~7.4 Jy (NOT part of the CP)

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• For this imaging run, we necessitate high angular resolution:
  1) Thus we need to be diffracion-limited at 10 microns, which occurs with a seeing
   of 0.8" in the optical.
  2) Since we image faint structure, we necessitate optimal atmospheric conditions
   (photometric) in order to have minimum flux losses.

Time-Critical Aspects

• - We necessitate to be diffraction limited in the N band. Thus we requested
   observations at low airmass. We would like to have the observations within 1.2 maximum
   at periods indicated in Time intervals.
  - During data reduction, in order to perform appropriate centering of the 20 mu
   image on the 10 mu image at the pointing accuracy of the telescope, it is mandatory
   that 20 mu images are done immediately after the 10 mu images, with only the change
   of filters between the two set of data.
  
  It is important that this time-critical aspect can be respected.

Special Calibration Information

• For this run, we request the observation of 2 reference stars in the following
   order
  
  1) Observation of the reference star HD31767 (NOT part of the CP) BEFORE the science
   OB. We submitted a specific calibration OB.
  2) Observation of the reference star HD34055 (NOT part of the CP) AFTER the science
   OB. We submitted a specific calibration OB for HD34055.
