Optical Filters . WFPC2 features two solar-blind Wood's filters, for FUV (<2000 ) imaging. ... These Wood's filters have a broad bandpass from 1200 to 2100 with visible-light transmission lower than 10^-8. ... In such cases, a Wood's filter (or "solar blind" detector as on STIS) is essential for FUV imaging so that the visible light leak does not dominate the observation. ... Two similar Wood's filters (F160AW and F160BW) were mounted in SOFA wheel 1 to provide some redundancy. ...

... The tracking (i.e. unguided) performance of the United Kingdom Infra-Red Telescope (UKIRT) relies on the accuracy of its 24 bit absolute encoders. These have been long known to generate two systematic errors. The first is a periodic error resulting from the encoder deriving the last 8 resolution bits by interpolation between the rulings on its code disk. ... To estimate the measurement errors we introduce a periodic filter to model and a Kalman filter to model . ...
