Major Instrument Modes: Aladdin JHK imaging, M-MR and L-LR spectroscopy

RA Range: 8.5-9

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance):
0.8 2CLR 1.5 1.0 30.


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


Special Remarks:
Schedule IRAS08621 JHK Aladdin imaging at the end of the night (bright sources)


 

DDT program on embedded YSOs from SIRTF project:
JHK Aladdin imaging and M-MR spectroscopy of IRAS 08621-5100, 
as well as M-MR and L-LR spectroscopy of HH46-47.
The JHK imaging field contains bright sources (K=9.0); a waiver has been
granted. This bright source itself will saturate, the users are interested in
high sensitivity of nearby sources. 
PLEASE SCHEDULE THE JHK IMAGING AT THE END OF THE NIGHT!
For spectroscopy, own telluric standards are provided. There are special
constraints on the spectroscopy program, namely airmass < 1.3, 
humidity < 30%, airmass difference between object and telluric standard
< 0.1. The latter is considered most important. The users are aware that
special constraints are on a best-effort basis.
!Given the coordinates of science objects and standard stars, a better
airmass difference can currently be reached if the standard star is
observed first, followed by the science target, and not vice versa.
An optimum time is to start with the standard star at HA~-2:30h !
Nov. or early Dec. is preferred because of early SIRTF press releases.
