Nickel Andor iKon-L 936 coordinates
coordinates for Andor iKon-L 936 as used for Nickel Direct
as a PDF file
This camera was installed in 2025.
The detector is Teledyne e2v
CCD42-40 in an
Andor iKon-L 936
where the vendor modified the readout software to provide some
overscan columns.

as a PDF file
The field of view of the guide CCD in direct mode would be about 7
arcmin (N/S) x 10 arcmin (E/W) but that is heavily vignetted.
These diagrams are a synthesis of the contents of what should be
several separate diagrams and documents.
The engineering diagram documenting the Nickel direct focal plane
should not include
-
the device name of the CCD
-
the designations of the video inputs
-
the designations of the amplifier types
-
the PANE coordinates
This is a draft. It all deserves double checking.
Please let me know if anything seems awry.
The FITS coordinates can be redefined, but the current
coordinates indicate the manner in which the ucam
code writes the pixels into the FITS image array.
