General Description

This program aims at a full MR K band visibility spectrum (MR2.1 and MR2.3)
 of a post-AGB star
to measure the intensity profile of the mass-loss envelope and to look for asymmetries
 of it.
Please try to observe a cal/sci/cal/sci sequence for each mode, if it fits into
 the 
1 hour allocation.

2 hours in priority A have been allocated to this program, which allows to observe
 one target
in both setups.

The primary target is AR Pup. It is at RA 08:03, Dec -36. It can be observed from
 LST 4:25h on
with airmass >1.5, i.e. observations can start 1.5 hours before the start of
 twilight. Please feel
free to continue half an hour into twilight. This target is at about the official
 limit of Kcorr=7,
maybe a little bit below.

Since this is an A-ranked program, we hope that the main target, AR Pup, can be
 done. However,
we have also submitted two alternative targets from the phase 1 proposal, IRAS 19125+0343
 at the
beginning of the night, and HM Aqr during the first half of the night. However,
 these sources
are fainter, somewhat below the magnitude limit, but should work if the conditions
 are good.

Calibrators are from CalVin, except HD213822 for HM Aqr, which is form a 2Mass/Simbad
 query.
