General Description

This run performs VISIR imaging of IC4662.  The VISIR pre-imaging (run
 D) shows mid-IR sources at the radio positions A1 and A2 indicated by circles in
 the finding chart.  The sources are about 11" apart in the E-W direction, with the
 brighter source A1 to the W.  In Q2 both sources were detected, but in SiC, not
 all frames showed an obvious source.  Source A1 has a flux of about 100 mJy in Q2;
 source A2 has less 30 mJy in Q2.  Because the sources are so faint, in this run
 we request additional imaging in these bands to create an SED, rather than attempt
 spectroscopy.  We chose a parallel chop-nod sequence with 20" throw.  The finding
 chart shows the non-rotated VISIR FOV and chop FOV.  Telescope chop PA is 320 deg.
  Telescope rotator angle is 345 deg.

Waiver Requests

A waiver request was submitted at 6am, Thurs. 24 Feb (waiverID: 075.B-0580A.01)
 and subsequently granted, allowing to split the run into pre-imaging and spectroscopy
 parts.
