General Description

• This is a straightforward PAH1 imaging of the globular cluster NGC104
   (also known as 47Tucanae).
  
  Eleven (11) fields are observed. Each field has 3 (1-hour) OBs, except for F1 (field#1)
   which has 4 OBs.
  It is fundamental that the 3 OBs of one pointing are finished before a new field
   is started, this is 
  regulated by the priority parameter.
  
  We choosed a bright guide-star from our BVI imaging @2.2m telescope data. This star
   is found at 4.5 arcmin 
  from the most distant of our fields. This is a bright star (V=11.907) and should
   be easily picked.
  
  It is fundamenal that the same guide-star is used for all fields and all OBs. Thus
   If, by chance, the TiO has difficulty 
  with the choosen star, please please please make sure that whatever new guide-star
   is used also for ALL other OBs (either 
  edit the OB on the fly or, or simply inform the P.I. and he will do it).
  
  Given the small field of view of VISIR, it is important to use the same guide star
   because we are using an 
  acquisition  preset template and few arcsecs of misaligment might compromise our
   strategy of having overlapping 
  fields (fundamental to tie the zero points of the single fields).
  
  Each single field has at least one bright star that should be visible by (more or
   less) half the 
  chopping/nodding cycles, however if the same guide star is used then there is no
   need to worry about identifying 
  our target because we are targeting groups of stars.
  
  This is the only and major constraint, otherwise we believe to have  put  relaxed
   observing conditions.
  
  Standard calibrations provided by the observatory are sufficient.
  
  If possible, the P.I. would appreciate if he can have access to the data once the
   first field is finished. 
  
  Thanks

Waiver Requests

• No Waiver Request was submitted. Indeed, all OBs respect the 1:00 hour
   limit.

Critical Observing Condition Constraints

• No critical observation conditions are necesary. 
  Other that respecting the "constraint set" that we provided 
  (1.2",THIN,Airmass<=2, lunar illum.<1 and moon distance >15) 
  we don't need anything else.

Time-Critical Aspects

• No time critical aspects are required.

Special Execution Requirements

• As written in the README, please finish one field (3 OBs) before starting
   another field.

Special Calibration Information

• Standard calibrations provided by the Paranal Observatory are sufficient.

ToO Information

• No.
