Estimated Total Execution Time (hours, including overheads)

• 3 hours 59 minutes (we were allocated 4 hours).

General Description

• Dear observer
  
  This is a "simple" observing program, aimed at obtaining multiple and dithered images
   of the outer parts of the Small Magellanic Cloud galaxy. Our analysis will be both
   photometric and astrometric.
  We do not need photometric conditions, however we seek good quality imaging, in
   particular, the stars need to be well-centered (and not allungated) so as to enable
   an astrometric comparison with 
  a previous 2001 epoch observations. We therefore kindly ask that the focusing is
   done before taking the images.
  
  In brief, we intend to observe 2 adjacent SMC fields as follows:
  
  (A) Field 1= This field has the HIGHEST PRIORITY: we intend to obtain 
  1) 16 images through the R filter 
  2)  3 images through the Washington M     filter
  3)  3 images through the Washington DDO51 filter
  
  The 16 R images were divided in 2 OBs so as not to exceed the 1 hour limit.
  
  (B) Field 2= This field has the SECOND PRIORITY: we intend to obtain
  1) 3 images in the B filter
  2) 3 images in the R filter
  3) 3 images in Washington M filter
  4) 3 images in Washington DDO51 filter
  
  All OBs for Field 1 should be done before attempting Field 2.
  
  We made different OBs for different filters so as to make the program execuation
   flexibale.
  
  We have included Sky Flat-Field OBs for the Washington-M and 513/15 filters since
   these 
  are not standard filters. Waiver was sent to be sure that the these extra flats
   will not be 
  charged from our allocated time, and we recieved a positive answer.

Waiver Requests

• We have asked the employment of two non-standard filters (Washington M
   and DDO51). We sent a waiver
  to make sure that the flat-fields of these filters would not be charged from our
   allocated time.
  We recieved a positive answer (see below).

   Dear Dr. Momany,
  
    I am pleased to let you know that the requested change in filters is
  granted. Indeed, the flats needed, which are not a part of the
  calibration plan, are not charged against the time allocation.
  
    Best regards,

Critical Observing Condition Constraints

• We do NOT need the night to be photometric.
  It is enough that it is CLEAR.
  
  Given the coordinates of our target field, we relaxed our seeing observing 
  constraint to 1.4 arcsec, and the airmass to 1.7.
  
  However, it remains important that the stars are well-focused.

Time-Critical Aspects

• Not needed.

Special Execution Requirements

• All OBs of Field 1 (HIGHEST PRIORITY) must be done before Field 2.

Special Calibration Information

• No aditional calibrations are required. 
  
  Overall, for our observations we need standard calibrations:
  
  1) 5 Bias images.
  2) 5 flat-fields images with good S/N (around 25000).
  
  The filters we intend to use are the B, R, Washington M, and Washington DDO51 (513/37
   in the WFI filter list).
