Estimated Total Execution Time (hours, including overheads)

• 06:00:00

General Description

• Low resolution spectroscopy (8.5 and 12.4 mu) of three young targets with
   circusmtellar
  matter. Two targets will be placed within the slit and observed simultaneously (OBs:
   170*).
  The third target is a single object but we have defined a rotator angle to include
   its extended
  emission within the slit (OBs: 177*).
  The most critical parts of the program are:
  (i)  the acquisition, since the targets are faint 
  (ii) the chop throw: for two OBs (pr170*) it MUST BE CHANGED 
  TO 6"  by the  Night Astronomer. Please, CHECK the Special Execution requirements!!

Waiver Requests

• 1 Waiver submitted 276.C-5025A.01 on 13/01/06 to use a chop throw of 6".
  Accepted on 23/01/06 under these conditions:
  - The OBs must contain the same guide star and observational parameters 
  (rot.offangle and chop.posang) used in previous observations, in order 
  to avoid the overlap of the two autoguider boxes.
  WE have used the requested values in the submitted OBs: pr170_337_8 and pr170_337_12.

Special Execution Requirements

• OBs pr170_337_*: 
  Two targets must be placed within the slit (the brighter one in the center).
  The finding chart shows the VISIR acquisition image obtained last year with the
   two sources.
  Look for the bright reference stars (marked as ref 1 and ref2 in the finding chart)
  to identify the targets.
  !!!!!!!!!!IMPORTANT!!!!!!!
  -->NOTE TO THE Night Astronomer: A WAIVER HAS BEEN GRANTED TO CHANGE THE CHOP
   THROW  TO 6" IN THE OBs pr170_337_12 and pr170_337_8. Please, change it MANUALLY.
  --> NOTE to the TIO: We have chosen a guide star that worked fine in previous
   observations. Please,  set the guide probe orientation (positive or negative (=alternate))
   to ensure that the boxes do not overlap. 
  OBs pr177_*:
  Long acquisitions (3 minutes)
  Two Finding charts are provided:
  FC1: VISIR PAH1/SF deep image of the target showing the extended tail to be placed
   
  within the slit.
  FC2: VISIR/N_SW acquisition image with the expected position of the target.
  We have submitted two OBs per setup with two different chop throws (10" and 11").
   
  It would be great if you could execute the 2 OBs consecutively but this is not critical.
