... example, note below the dramatic speedup in searching a 1 Gb file using an AND filter, even when one of the columns (pha) has no index : time fundisp \ huge.fits'[idx_activate=0,idx_debug=1,pha= 2348 4000 4000 1]' \ x y pha x y pha ---------- ----------- ---------- 3999.48 4000.47 2348 3999.48 4000.47 2348 3999.48 4000.47 2348 3999.48 4000.47 2348 3999.48 4000.47 2348 ... Currently, indexed filtering only works with FITS binary tables and raw event files. ...

... 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. ...

... The file lpf_pwr.txt contains data from a hardware simulation of the low-pass filter. The first column is the baseband frequency (in MHz) into the filter and the second column is the power output of the filter (relative to the input power, in dB). ... The simulation clearly shows the ~0.06dB Gibbs phenomenon ripple in the filter. ... The plot below superimposes the filter data ( red line ) with values measured by integrating a noise source for a long time on real hardware (white line). ...

... Apache HTTP Server Version 2.2 . ... This document describes the use of filters in Apache. ... The Filter Chain is available in Apache 2.0 and higher, and enables applications to process incoming and outgoing data in a highly flexible and configurable manner, regardless of where the data comes from. ... A wider range of applications are implemented by third-party filter modules available from modules.apache.org and elsewhere. ... There are two ways to use filtering: Simple and Dynamic. ...
