Filter shifts

On October 9, 2005 CONICA images have been taken with the pinhole array & different filters with and without neutral density. These data can be retrieved from here. They are meant to help estimating the astrometric shift existing between the different filters.

Table of data taken

All data have been taken with the S27 camera.Detailled list of settings here

Data with Full Lyot stop
Data with Neutral Density (ND_Short)
Ks , (Different lamp settings) Ks Ks , (Different lamp settings) Ks
H , (Different lamp settings) H H , (Different lamp settings) H
J , (Different lamp settings) J J , (Different lamp settings) J
NB_1.04 NB_1.04
NB_1.09 NB_1.09
NB_1.24 NB_1.24
NB_1.28 NB_1.28
NB_1.64 NB_1.64
NB_1.75 NB_1.75
NB_2.12 NB_2.12
NB_2.17 NB_2.17

Some results

The following provides the centroid position for 5 selected holes for each filter measured, as well as the corresponding light intensity.With the exception of the data taken with different lamp settings (seeabove table) for J, H, Ks, all data have been taken with a constant lamp setting aiming at getting an idea of the 'spectral effect' of the neutral density. For this purpose, frames with the same settings but with the lamp off have been taken (to remove the thermal effect related to the filter and not to the lamp).
