General Description

High resolution infrared spectroscopy of the nebular emission near the
 Irc2 source in Orion.
The goal is to obtain spectra of the nebular emission, excellent pointing accuracy
 is not required,
the OBs are set up to acquire BN (the brightest star-like object in the region,
 then offset to the 
position required for the spectroscopy. 

The sky are taken far away from the nebula. Be sure to have the same VLT Guide star
 every time an ON frame is taken.

The priority order for observation (noted in the OBs as well) is the following:

1- K spectroscopy of slit 1 (2 blocks: Kspec_1_a and Kspec_1_b)
2- K spectroscopy of slit 2 (2 blocks: Kspec_2_a and Kspec_2_b)
3- H spectroscopy of slit 1 (2 blocks: Hspec_1_a and Hspec_1_b)
4- H spectroscopy of slit 2 (2 blocks: Hspec_2_a and Hspec_2_b)

Special Execution Requirements

As noted by Elena Mason (cf tickets USD-14752 and USD-14753), guide probe
 fails in finding guide star automatically. Therefore, when observing this programme,
 please select manually the following GS:

RA=053456.6 DEC=-052304.6  for all OBs using slit position 1 (spec_1)

RA=053527.58 DEC=-051305.6  for all OBs using slit position 2 (spec_2)
