General Description

The goal of this project is to perform high angular resolution
spectroscopic observation of ~3um dust features in disks around intermediate
mass young stars. The star itself is bright enough to be used as 
optical wavefront reference. The star is also the brightest object
within the field of view at L-band, we have set the acquisition filters
following the prescriptions in the manual. 
HD100546 has L=4.2, we are using L_prime+ND_Long for acquisition
HD100453 has L=4.4, we are using L_prime+ND_Long for acquisition
Spectra will be taken on 7 (or 9) slit positions (spaced of 0.043") along two perpendicular
 axis of the disk.
The spectroscopic OBs require acquisition of the star, which should be bright 
enough for easy acquisition, and then for each of the 7 (or 9) slit positions 
an ABBA cycle with 1min integration per position will be performed.

Waiver Requests

We request the possibility to do OBs (HD100546-a1-a2) of 1h08mn22s in
 order to take spectra on 9 slit positions and to avoid intercalibration problems.
Our request has been granted, under one special condition.  The condition is that
 if the observing conditions
degrade in violation of the your Constraint Set values after the first hour of execution,
 the OB will not be repeated.
