General Description

The observations proposed aim at finding the most embedded population
 of stars in regions of recent or on-going high-mass star formation.  In the case
 of regions sampled by IRAC/GLIMPSE observations (10-70deg on both sides of the Galactic
 Centre), the core of emission saturates even 2 second exposures. In this cases,
 the VISIR data only samples the brightest area.
We have selected a blind preset Acquisition that shifts the first position to the
 South-East corner of the field.
The GenericChopNod template has been used to raster the areas we want to observe,
 with a reference position (A) and subsequent nodding offsets that map the region.
Our finding charts show the region to map (continuous red square) and the different
 nodding pointings (Bi) required to map with the 32 arcsecs camera field with a throw
 of 16 arcsec (yellow points). We have indicated reference chopping position and
 first nodding offset pattern (discontinuous squares). An offset of thow/2. has been
 added to the pointings.  The order of the OB pointings is from east to west and
 from south to north.

Waiver Requests

We requested a waiver to submit OBs of duration longer than 1 hour, but
 always shorter than two hours ( 24 October 2006)
