 New DDT-ToO program aimed at measuring the C12/C13 and N14/N15 isotopic 
ratios from high-res and high S/N spectra of comet C/2000 WM1 LINEAR. 
These abundance ratios are efficient probes of the origin of solar 
system matter. 

 The ToO nature of this program comes from the fact that observations 
need to be carried out between March 4 and 15. Only 50min are available 
at the end of each night. Each OB specifies when execution should start - 
if not fulfilled, coordinates need to be updated. Please cf README file 
for a detailed description. 

 Requirements: program needs special calibrations, i.e. a twilight sky 
spectrum (OBs have already been prepared) and standard calibrations 
for each night during which an OB is executed. Contact Person is Emmanuel 
Jehin.
