These calibration les contain each 16 extensions for rst and 16 extensions for second order background spectra. ...

Next: Photometry Up: Regions and Source Parameters Previous: *imcnts* - Find counts . This task (developed for use with optical images, but also useful with x-ray data) will quickly compute location, size, ellipticity, and position angle of sources. ... User can generate contour plots of any portion of the image and count rates in slices through the image. The program is advertised as ``quick [optical] photometry''. input file: rp110590_im1.imh . output file: logfile . ... Photometry . ...

... We have developed a new extraction software package called aXe that was specifically designed to handle the ACS spectrophotometric data. ... The aXe software was designed to extract spectra in a consistent manner from all the slitless spectroscopy modes provided by the Advanced Camera for Surveys (ACS) that was installed on the Hubble Space Telescope in February 2002. ... The extraction process is a set of well isolated steps that can be individually applied and tweaked by the user (Figure 1 ). ...

... All STIS data products are FITS files. Images and two-dimensional spectroscopic data are stored in FITS image extension files, which can be directly manipulated, without conversion, in the IRAF/STSDAS environment. These FITS image extension files allow an associated set of STIS science exposures, processed through calibration as a single unit, to be packaged into a single file. ... A triplet of FITS image extensions corresponds to each exposure in a STIS data file: . ... array . ...

The FITS archive & data processing pipelines . ... The archived data are broad band images (BBI) and long-slit spectra (LSS) plus their associated template and calibration files. The data in HFA can enter into the HyperLeda processing pipeline and the results can be freely downloaded. ... Definition of the file system (structure of the archive) . ... The coordinate systems must be updated when the data (pixel data, other keywords, related tables) are altered (eg. rebinning of the image). ...

slitless -- Extract a spectrum from a direct/GRISM image pair slitless image grism output PARAMETERS . ... A two dimensional direct image to be used to select an object. grism . A two dimensional GRISM image containing slitless spectra of objects present in the direct image. output . ... Toggle whether or not a background estimate is subtracted from the extracted object spectrum. mingood = INDEF . Pixels of the grism image with values smaller than this are ignored. maxgood = INDEF . ...

... There are compelling reasons for the pulsar community to utilise a standard data storage format. For example, standardisation of file formats significantly decreases the amount of effort required to integrate new instruments into the analysis chain. ... Accordingly, we have defined PSRFITS as a standard FITS-based format for pulsar data files. ... For example, the first line of Processing History HDU contains information about the data acquisition program and the initial structure of the file. ...
