The Linear Ramp Filters (LRFs) provide a narrow band ( ) imaging capability which is continuously tunable from 3710е to 9762е. These are essentially a collection of narrow band interference filters whose central wavelength varies with position on the filter glass. ... If it is necessary to know which CCD will be used, observers can consult Table 3.7 or Table 3.8 , or use the on-line LRF calculator tool on the WFPC2 WWW pages. ... See Linear Ramp Filters for further details on LRFs.) ...

... NICS will be the only infrared instrument for the first light of the TNG; as a consequence, we decided to incorporate a sufficient degree of operation flexibility by providing the instrument with six different observing modes, three aimed at imaging and three at spectroscopy: . ... It will be possible to use the narrow band filters as order sorters; this will allow to perform high resolution long-slit spectroscopy in the wavelength ranges covered by the available narrow band filters. ...

... Special problems arise with filters intended to measure red leaks in blue and ultraviolet filters. ... The column named REDLEAK contains an 8-character string that specifies the treatment of red leaks in short-wavelength filters. Possible values are 'MEASURED' if the red leak is measured by observations through a filter that isolates the leak; 'BLOCKED' if a copper-sulfate or other blocking filter is used; or 'IGNORED' if the leak is neither measured nor blocked. ...

We have been upgrading the software front-end to WASP (Wideband Autocorrelating SPectrometer, operating from 800 to 4000 MHz) from Lynx-OS to Real-Time Linux and will discuss Real-Time software aspects. We are using a standard parallel ``PIO'' card to receive data from the spectrometer and standard GPIB interfaces that drive a frequency synthesizer for bandpass calibration. WASP and its front-end computer are fully mobile and can be taken to any suitable radio telescope. ...
