General Description

• This is the TOO part of our NACO+VISIR monitoring programme of the T Tau
   system,
  aimed particularly at characterizing the (sometimes very fast) photometric variations
  in Sa, the more massive component of the southern close binary. For a more detailed
  description, see the readme of the main monitoring programme (084.C-0783(A+B)).
   
  Here we list only information specific to the TOO part.
  
  The normal monitoring programme consists of "monthly" observations during the whole
   of
  P84, and "weekly" observations during two months (preferably november+december).
   The
  TOO will be triggered in case substantial variations from one week to the next are
  detected in the weekly monitoring period. The TOO comprises even more intensive
  monitoring, with one observation every 1-2 days (do whatever is feasible on the
  mountain, and "every day" is not necessarily better than "every two days". A mixture
  of 1 and 2 day intervals would be ideal). 
  
  Though direct interaction with PI's is not part of standard procedures, we would
  greatly appreciate it if you could send us (boekel@mpia.de, ratzka@usm.uni-muenchen.de)
  a quick email saying "we observed T Tau last night with NACO (VISIR)", in case you
   did.
  
  many thanks for your help, we hope you'll have fun executing this programme, and
  that we will detect some nice and fast variations - those are the ones from which
  we learn most!
  
  with best regards, on behalf of the team

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• none other than given in the OBs

Time-Critical Aspects

• During the optional, intensive monitoring part of the campaign (i.e. this
   TOO programme),
  it is important that the NACO and VISIR observations are done during the same night,
  if at all possible, since we seek to characterize SED variations on time scales
   of days.

ToO Information

• The TOO part consists of observations identical to those in the main monitoring
  programme, except that the frequency of execution is increased to once every
  1-2 days (a mixture of 1 and 2 day intervals is ideal).
  For the TOO observations, it is important that the NACO and VISIR observations
  are performed during the same night, whenever possible.
