General Description
We have conducted with NACO a large-scale adaptive optics search for stellar
companions to nearby stars with and without planets. To recognize true companions
from the many background stars we rely on two-epoch astrometry. This observing run
aims at completing the second-epoch measurements of the 19 targets from our sample
that need such measurements.
In a general way, we wish to keep the peak count below 10000 ADU. PLEASE ADJUST
DIT*NDIT SUCH THAT THE PEAK COUNT BE BETWEEN 8000 AND 8500 ADU.
FIELD CENTERING: For the targets listed below, the coordinates of the target field
have been set such that the field of view be centered between the target and the
companion candidate. The field centering is (approximately) reported graphically
on the finding charts. The actual centering is according to the following numbers:
HD 18194: field centered at 4.5 arcsec, PA = 83 deg from R1;
HD 168746: field centered at 7 arcsec, PA = 307 deg from R1;
HD 171587: field centered at 6 arcsec, PA = 246 deg from R1;
HD 169830: field centered at 11 arcsec, PA = 265 deg from R1 (no high-resolution
finding chart available);
HD 204313: field centered at 2.77 arcsec, PA = 206 from R1;
IDS 21506S5133: field centered at 4.17 arcsec, PA = 350 from R1.
For the other targets, fields are centered on target.
HD 41004 has a companion at sep = 0.54 arcsec and PA = 176 arcsec (Hipparcos Catalog).
HD 169830 has a tentative companion at sep = 11 arcsec, PA = 265 deg (Raghavan et
al. 2006). Other companion candidates are indicated on the finding charts.
IDS 21506S5133 and TCC094 are two astromteric calibration fields. At least one of
those should be observed early in the observing sequence.
No PSF reference star will be observed for this program.

Pre-imaging Requirements
Source(s) of Pre-imaging
Pre-imaging sources not listed above
Do all your OBs comply with the instrument-specific requirements listed
on the instrument-specific Phase 2 web page ?
If this is a pre-imaging run, did you select PRE-IMAGING for the Observing
Category for each Observing Template ?
Do all your finding charts comply with both the general and instrument-specific
Phase 2 Web Pages ?
If you submitted OBs for standard stars, did you specify the magnitude
and spectral type of all standard stars in the OBs ?
Have you included OBs for any calibrations that you need but which are
not part of the Calibration Plan ?
If you are observing Moving Targets, have you attached suitable ephemeris
files to your OBs?
If you have preferences which OBs should be executed first, did you make
use of the User Priority field in the OBs ?
If this is a run that requires coordinated observations with other facilities,
did you give proper instructions in the Time-Critical Aspects Section ?
If you have PSF reference star OBs, do the names of those OBs begin with
PSF_ ?
If there are Finding Charts attached to your OBs, is the field-of-view
of at least one of these charts 2' x 2' (with clearly labelled field orientation)
?
Have you clearly marked and labelled your wavefront reference objects
R1, R2, R3, ... (as specified in the NAOS Preparation Software) on your Finding
Charts ?
Have you specified the magnitude of the brightest object in the field-of-view
for each OB ?
Are there objects in any of your fields (including standard stars) which
are brighter than the limits specified in the User Manual and on NACO web Pages
?
If the previous answer is yes, have you given a list of OBs and a justification
for the brightness limit violation in the general description field ?
