General Description

We try to image gas emission lines from an edge-on circumstellar disk.
 The center of the ARGUS array will be located on the disk just 3.1 arcsec outside
 the primary star, which is _very_ bright (V=3.86; see proposal for cartoon). With
 the 1:1.66 lens, the ARGUS width is 4.2 arcsec, so the distance between the star
 and the ARGUS edge should be 1 arcsec.

The guide star we picked is fairly close to the center, as we are not interested
 in targets outside the ARGUS array.

We have placed the ARGUS sky fibers on fixed coordinates for all OBs, which correspond
 to empty sky except in two cases, which are put on background stars with B = 10
 and 12 mag.

The four OBs of this run correspond to two positions, one on each side of the disk.
 Each position is covered by two OBs, which have ARGUS position angles differing
 by 180 degrees.

All coordinates come from UCAC2 and have been computed for epoch 2009.0 (equinox
 J2000) taking into account proper motion, and should be good to 0.1 arcsec.
