Major Instrument Modes: UVES Dic1_346+580

RA Range: 17.7h

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance): 0.8, CLR, 1.3, 0.5, 30

Pre-imaging run?	No!	Chilean run?	No!	Special calibrations?	No!
Time critical?	No!	ToO?	No!	Carry-over run?	No!

Special Remarks:

 
 
 One single Dic1 exposure (~1h long) of the recently identified 
companion (probably early G-type, V = 17.0) of the milliarcsec 
pulsar PSR J1740-5340, aimed at measuring the mass of the radio 
pulsar, thus constraining the equation of state of matter at 
extreme densities. 

 The source is located in the globular cluster NGC 6397, 29" 
east and 16" south of the core.  However, the field is not 
hopelessly crowded: the nearest neighbor star is about 1.2" to 
the north west. The object is marked with a small circle in the 
center of the finding chart.
