Major Instrument Modes: UVES/RED

RA Range:07:08-11:00 MOVING TARGET!

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance):
1.0 2CLR 2.0 1.0 30

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

Special Remarks:
observations must be executed before epochs that vary from target to target!

 
 
This is a quite complicated UVES programme aimed at measuring wind
speeds in Titan atmosphere. The slit has to be positioned
perpendicular to the rotation axis and, therefore, the PA has to be set
according to the exact observation time. The user has supplied appropriate
.eph files which contain PA for each target and epoch.
Also, differential tracking rates are given with a very fine time step, in
order to allow for a good guiding.

Titan: 001.eph-002.eph

Therefore, the night astronomer is requested to enter target coordinates,
diff. tracking rates and PA at execution time.

OBs have different time constraints:

MOV_Titan_4EQ      : before May 1
MOV_Titan_disk_1,2 : before May 5
MOV_Titan_2EQ_1,2  : before May 8
MOV_Titan_NS       : before May 12

For the OB priorities, see the README file.

The PI is really concerned about object drifts. For this he asks the night
astronomer to inspect the slit centering frequently, and to apply suitable
corrections if needed. Target cenetering is crucial for the science.

This is the acquisition procedure that has to be followed:

1) set a pause in Bob on the first observing template;
2) start the OB and acquire the target as usual using the acquisition template,
3) while the  first observing template is paused, start secondary guiding and 
   wait until residuals have dropped below 0.1" (following the normal loop 
   frequency recommendations);
4) continue the observing template;
5) just before the first exposure a control SV image should be saved;



IMPORTANT NOTE: the PI asks to save a sequence of 2 min (with 5 sec frequency)
Slit Viewer images, to check the slit centering. The PI is aware that this will
be done on a "best effort basis". If obtained, the data should be saved and
delivered to the user via USG. Send an e-mail to usd-help@eso.org indicating
the program ID and the place where the images can be retrieved via ftp.
