General Description

• VISIR is used in its echelle mode to spectrally resolve [Ne II] emission
   toward 12 T Tauri stars previously observed with Spitzer.
  
  We use the long-slit high-resolution mode with VISIR and the standard procedure
   of nodding along the slit (to double the efficiency). Because the continuum flux
    near the [Ne II] emission line is weak for some sources (~0.05\,Jy), we will acquire
   the targets with the spectro-imager on VISIR in combination with the [Ne II] filter.
  
  For each source a science and a calibration standard star ob, named CAL_
   is defined.

Waiver Requests

• No waiver requests submitted

Critical Observing Condition Constraints

• No critical observing condition constraints

Time-Critical Aspects

• No time-critical ascpects

Special Execution Requirements

• Acquisition on the peak of the emission near the specified coordinates.
   The requested sources are the brightest mid-IR sources within the VISIR field-of-view
   at each pointing.
  
  Expected 12.8 micron continuum fluxes based on Spitzer-IRS spectroscopy:
  	IRAS08267		300 mJy
  	WXCha			300 mJy
  	XXCha			100 mJy
  	UXTauA			100 mJy
  	V807Tau			200 mJy
  	LkCa15			100 mJy
  	IMLup			500 mJy
  	RXJ1615.3-3255		100 mJy
  	SSTc2d_J162145.1	 40 mJy
  	WL19			100 mJy
  	WL20S			900 mJy
  	IRS60			700 mJy
  
  For some sources two OBs excist named -1 and -2 with
   associated cal OBs. If possible it would be preferred to have these scheduled contiguesly
   which will allow us to perform a better standard star correction to the combined
   data. The executed order of science and calibration ob is left to the discretion
   of the observer, so e.g.
  	WXCha-1 # CAL_WXCha-1 # WXCha-2 # CAL_WXCha-2
  		or 
  	CAL_WXCha-1 # WXCha-1 # CAL_WXCha-2 # WXCha-2
  depending which sequence is considered optimal to minimize the difference in airmass
   from start to end.
  This applies to IMLup, IRAS08267-3336, LkCa15, UXTauA, WL19, WXCha and XXCha 
  
  If possible we would also like to see the following sources (plus their cal obs)
   scheduled contiguesly:
   - WXCha and XXCha
   - UXCha, V807Tau and LkCA15
   - WL19, WL20S and IRS60
  If these are scheduled contiguesly it will improve the calibration since then multiple
   standard star observations will be available allowing e.g. to model time variations
   in the standard star correction.
  The executed order of science and calibration ob is left to the discretion of the
   observer to minimize the difference in airmass.

Special Calibration Information

• For each source two OBs are defined, a science and calibration OB (named
   CAL_) which should be observed back-to-back. It is left to the discretion
   of the observer to observe the calibration OB before or after the science OB to
   minimize the difference in airmass. This may be relevant i.p. for long integration
   science observations.
