Major Instrument Modes: UVES Dic2_437+860

RA Range: 9.5h

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance): 1.0, CLR, 2.5, 1.0, 30


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


Special Remarks:
new DDT *urgent* program (newly discovered milli-sec X-ray pulsar is fading away fast) using non-std 2x3 binning


 
 
 DDT program on the newly discovered accreting millisecond X-ray pulsar 
XTE J0929-314 (orbital period of 43min), consisting of 5 1h-long OBs. 
Although they do not need to be observed during 5 consecutive hours, it 
would be important to execute more than one OB on a given night (in this 
way, it will be possible to assess phase to phase variations, if any, and 
the extra calibration load due to an approved non-std setting - see below - 
will affect a smaller number of nights). 

 Requirements: execution is quite urgent (RA=9.5h and target may be fading). 
Non-std 2x3 binning mode approved by A.Kaufer on 21.5.02. No special 
calOB submitted because already available on the mountain (AKa). FC should 
do it (label '2x2 arcsec' should clearly read '2x2 arcmin').
