position

IDL_Type:long Units:unitless Count:1

Description: The reported position.

name

IDL_Type:string IDL_Size:256 Units:unitless Count:1

Description: Name of the filter.

centralWavelength

IDL_Type:float Units:nm Count:1

Description: Wavelength for which optical system will be optimized in units of nm.

Approximations are sufficient as the focus dependence on wavelength is weak.

focusOffset

IDL_Type:float Units:mm Count:1

Description: Focus offset to be applied on the secondary mirror in units of mm, relative to no glass

being installed. Positive values push the secondary down and increase the back focal distance, therefore adding glass thickness will result in positive focus offsets.

pointingOffsets

IDL_Type:float Units:arcsec Count:2

Description: Pointing offset to be applied to the boresight in units of arcseconds, relative

to no glass being installed. Relative to the center of the detector,positive X-values result in moving along rows, to higher pixel values

focusOffset

IDL_Type:float Units:mm Count:1

Description: Focus offset to be applied on the secondary mirror in units of mm, relative to no glass

being installed. Positive values push the secondary down and increase the back focal distance, therefore adding glass thickness will result in positive focus offsets.
