Programme Description
=====================

General Overview
----------------
The N-band luminosity towards the centers of galaxies has long been known 
(Rieke & Lebofsky, 1978, ApJ 220, L38) to be a trustful indicator of 
activity.  We wish to perform 10mic. imaging with VISIR at the VLT in our 
complete FIR--selected sample of spiral galaxies which contains some 160 
objects with S_100mu > 9 Jy (Albrecht et al., 2004, AA 414, 141).  
The targets for the observations proposed here have been selected according 
to their distance  to achieve a high spatial resolution and their 
IRAS 12mic. flux (> 0.4 Jy).

Two thirds of our objects show clear signs of central activity (starburst or
Sy2), the rest none.  As 10mic.  continuum emission traces hot dust (heated
either by OB stars or by an accretion black hole), the observations will serve
as an independent check of the present activity classification and possibly
detect new activity candidates.  In view of the high spatial rewsolution 
(0.3" at the VLT) and the relative proximity of the sources, in the case of 
a starburst the emission is expected to be resolved and we will be able to
delineate the structure of the starburst region.  If an AGN is the major 
energy source, the emission should be point-like.

OB Compliance Checks
====================

(Y = Yes, N = No, NA = Not Applicable)

Do all your OBs comply with the instrument specific requirements
listed on the instrument specific Phase 2 Web pages ? [Y/N/NA]
y
Do all your Finding Charts comply with the both the general and
instrument-specific finding chart requirements? [Y/N/NA]
na
If you submitted OBs for standard stars, did you specify the magnitude
and spectral type of all standard stars ? [Y/N/NA]
na
Have you included OBs for any calibrations that you need but 
which are not a part of the Calibration Plan?  [Y/N/NA]
na
[UVES only] Do all your UVES OBs use only the allowed templates listed
on the UVES Phase 2 Web pages ? [Y/N/NA]

[ISAAC only] Did you indicate the magnitude of the brightest star in the
field for ISAAC imaging observations? [Y/N/NA]

[ISAAC only] If you submitted OBs for standard stars, did you
use the provided StandardStar templates? [Y/N/NA]

[FLAMES only] Did you specify the hour angle range for which your Target
Setup files are valid ? [Y/N/NA]

[FLAMES only] Did you specify the S/N ratio (at some reference
wavelength and per single exposure) you expect to reach with these
observations? [Y/N/NA]

[VIMOS only] Did you specify suitable guide stars for all your OBs
using Guidecam? [Y/N/NA]

[VIMOS only] Did you check that the chosen guide stars are suitable for
all the offset positions and that they do not produce unacceptable
vignetting of the field of view? [Y/N/NA]

[MIDI only] Did you indicate for each science star OB the corresponding 
calibrator star OB name in the ReadMe file as well as in the comments 
of the OB ? [Y/N/NA]

[MIDI only] If you use calibrator stars which are not in the
CalVin database, did you specify their characteristics in the ReadMe 
file and in the OBs  ? [Y/N/NA]

If you answered "NO" to any of these questions, please revise your 
OBs *before* submission.
