... Cameras NIC1, and NIC2, each contain 3 polarizers, whose principal axes of transmission are separated by 120 degrees. ... As with the imaging filters, sensitivity information for the two sets of polarizers may be obtained from the Exposure Time Calculator. It gives the same information as was described in Chapter 4: namely a sensitivity curve, plotted as flux against time for a constant S/N ratio and an exposure exclusion curve for both point and extended sources. ...

Next: SettingStoring, and Up: CCD Reductions Previous: Nature of CCD . The CCD package provides a set of basic commands that perform the various calibration steps. ... When the context CCD is enabled, a keyword structure is created which contains the parameters for the calibration steps and to control these. ... Finally, keywords are created to contain the names of important frame descriptors, like the standard MIDAS descriptor for the exposure ( O_TIME ). ...

... The combined event list takes from the intermediate event lists all of the events (combined into a single table), the collections of CCD-specific exposure tables and Good Time Interval (GTI) tables, and the collections of node-specific bad pixel tables and rejectable pixel tables. Name collisions among tables copied in from the intermediate event lists are avoided by placing the corresponding CCD number at the eighth character of the extension name. ... table : EVENTS -- evlistcomb . ... int32 . ...

... The processing of these associated images presents new challenges to the HST data processing pipelines, which heretofore operated only on single images. ... Stage 1 (CALNICA) calibrates individual exposures without information from other members of the association. ... Stage 2 of calibration (CALNICB) only operates on associated images that have previously gone through CALNICA processing, and creates combined images for each distinct (non-overlapping) pointing within the association. ...

Next: *imcalc* - Obtain a Up: Calibration Previous: Exposure Map . Background maps are provided by the standard processing for all ROSAT and Einstein instruments. For the PSPC and IPC these are in three standard bands: soft, hard, and broad (Table 6.2). ... N.B.: ROSAT PSPC background maps in SASS 5-6 or higher are generated by smoothing a source-subtracted, exposure corrected image (see the ROSAT Data Products Guide). ... imcalc* - Obtain a background subtracted image for ROSAT PSPC Data . ...

Example FITS maps have been prepared for each of the projections described in Paper II , and separate FITS spectral data files are provided to illustrate the spectral representations described in Paper III . ...

60 PIN UNKNOWN CONNECTOR . The Audio/Video Input/Output Card has a separate connector called the DAV (digital audio video) connector. The DAV connector provides access to the Audio/Video card's 4:2:2 unscaled YUV video input data bus and associated control signals. By means of a 60-pin cable to the DAV connector, a PCI expansion card can gain access to the digital video bus on the Audio/Video Input/Output Card and use it to transfer real-time video data to the computer. ...
