Filter ID (?) :	Liverpool/IOI.J
Description (?) :	IO:I J filter
Phot.System (?) :	------
Detector Type (?) :	Photon counter
Band Name (?) :	J
Obs. Facility (?) :	LT
Instrument (?) :	IO:I
Comments (?) :	Transformed to operating temperature of filter on the basis of non-directly-measured assumptions. * The temperature of the cooled filter inside the cryostat is not directly measured. The array and other electronics are directly monitored, but not the filter itself. Thermal corrections are therefore based on our best estimate of the filter temperature being T_filt = -78C * The filter transmission was measured at 300K only. Transformation to operating temperature is based on the manufacturer's specification of typical performance.
