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

This is an IMAGING program of the young star HD163296
which includes: 

L-band direct imaging,
CORONOGRAPHIC H&K imaging
POLARIMETRY H&K imaging
 
The aim is to detect circumstellar matter
and protoplanetary objects around the target.

OB Information
==============

List of Science OBs with Associated Finding Charts
--------------------------------------------------

Total Number of Submitted Science OBs: 12
Total Number of Submitted Finding Charts: 2 

Ther are two finding charts:

HD163296fchart.ps : -corresponds to the TARGET
              -R image of a 2x2 arcmin region

HD162563fchart.ps : -corresponds to the PSF calibration star
               that will be used in the Coronographic and L-band obs.
              -R image of a 2x2 arcmin region

        
The OB Target is at the center of the finding chart.

The OB list contains:

HD163296_PSF_K        = HD163296fchart.ps
HD163296_Coro_K       = HD163296fchart.ps
HD162563_PSF_calib_K  = HD162563fchart.ps
HD162563_coro_calib_K = HD162563fchart.ps

HD163296_PSF_H        = HD163296fchart.ps
HD163296_Coro_H       = HD163296fchart.ps
HD162563_PSF_calib_H  = HD162563fchart.ps
HD162563_coro_calib_H = HD162563fchart.ps

HD163296L             = HD163296fchart.ps
HD162563L             = HD162563fchart.ps

HD163296_PolK   = HD163296fchart.ps
HD163296_PolH   = HD163296fchart.ps


NOTES FOR THE CORONOGRAPHIC OBSERVATIONS:

1. For the coronographic observations, this observing
sequence must be applied:

HD163296_PSF_K
HD163296_Coro_K

HD162563_PSF_calib_K
HD162563_coro_calib_K 

HD163296_PSF_K
HD163296_Coro_K
HD163296_Coro_K
HD163296_PSF_K

HD162563_coro_calib_K
HD162563_PSF_calib_K

(the same for the H-band filter)

2. If the selected PSF calibration star resulted to be a binary,
another star with similar spectral type and brigthness as the target
must be selected, for example: HD161644, HD162010, HD162492.

3. In the H&Kdirect imaging observation of the two stars (target and
PSF calibrator), the OBs are written to place the  object in the four 
quadrants of the detector. The four positions
are non symetric to correct later from possible reflections.




NOTES FOR THE L-BAND OBS:

The star must be initially placed at the center of the detector.
The OBs are written so that the star is observed in the 4 quadrants of 
the detector. The four positions are non symetric to avoid the 'reflex'
effect reported in the commisioning.


NOTES FOR THE POLARIMETRIC OBS:

1. The offset positions have been taken of 5 arsec at both sides of the
initial position. The right value to cover the whole field
is still not specified in the last version of teh manual, so it can
be replace with the exact value.

2. The polarimetric OBs contain short and long exposures.
The long ones will certainly saturate teh star but, given 
that they will provide information about the sorroundings of 
teh star, it is not a problem for our purposes.
