... 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. ...

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 types of respirators in use at APO are half-face, full face, and mask-style filter types. ... These respirators DO NOT supply oxygen. ... The observatory does not maintain Self Contained Breathing Apparatus (SCBA) for use and, consequently, materials that require them cannot be used. ... Whenever possible chose adequate ventilation over using a respirator. ... Oxygen monitors used for confined spaces may be used to monitor oxygen levels where respirators are required. ...

Consequently, the calibration for data collected using the hipass 1320 and the hipass 1370 filters only will be mis-calibrated (i.e. by using the opposite polarisation calibration data). ... It is now possible to select any bandpass filter that is not in the 1320 hipass band. ...

. NEVER look directly at the sun without a proper solar filter! . We have lots of different equipment available for use. Here you see our 6" solar filters. Our club always recommends that you use a FULL APERTURE solar filter. In the picture you will notice a TYPE 2 filter for VISUAL use and a TYPE 3 filter for PHOTOGRAPHIC use. Here is an easy way to remember which type solar filter you need for VISUAL OBSERVING: You have 2 EYES so you need a TYPE 2 filter!! .
