... 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. ...

... Previous: Background Fluctuation Analysis from the Multiscale Entropy . ... A new measure of information is defined which is based on noise modeling and incorporates resolution scale. Properties of this measure are discussed. ... Additionally it allows for image noise modeling, and subsequent noise removal. ... Hence information- and entropy-based processing technologies will be necessary for the effective design and implementation of large, future generation, image databases. ...

SHORT DESCRIPTIONS OF INSTRUMENTS . ... Particle detector RIEP-2802 was developed and built in Russia. ... The combined Soviet-French ONCH-TBF onboard instrument had in memory modes the data only from several filter-banks in the range from 10 Hz to 16 kHz (while in the real-time telemetry modes, the measurements included 5-component wave-form data in the range 10 Hz - 1.5 kHz for 3 magnetic and 2 electric field components, or a wide-band mode in the range 10 Hz - 15 kHz, and several filter banks). ...

Here is a description of the Filter/Driver Pack Plus release from Aldus. ... The Macintosh Filter/Driver Pack Plus includes several new and updated filters, including import filters for Microsoft Works 3.0 and MacWrite Pro files, as well as the most recent LaserWriter driver, version 8.1.1. ... The Filter/Driver Pack Plus also includes a patcher utility which will update PageMaker 5.0 to version 5.0a. This patcher corrects a handful of reported customer problems. ...

The basic characteristics of the instrument are set by the aperture, focal length and resolution of the image forming lens, the dispersion of the spectrometer, and the sensitivity of the detector. ... The lens is internally focused, and maintains acceptable focus (2 pixels in the detector plane) over a typical spectral coverage of one grating setting. ... along the spatial dimension of a 25mm square detector in the final spectral image plane the 400mm lens is 3.2њ. ... Diffraction grating . ...
