549. Introduction
Next: stecf.cplucy - Enhanced Two-channel Up: The ``stecf" IRAF Layered Previous: The ``stecf" IRAF Layered . For many years the ST-ECF has developed IRAF tasks and packages for HST and related data analysis. ... To allow wider and more efficient distribution and to bring all components to a uniform level of quality and documentation we have decided to combine these components into a standard-format IRAF package to be called ``stecf''. ...

550. stecf.cplucy - Enhanced Two-channel Photometric Restoration
... To address the problem of point-source photometry in restored images Lucy (1994) suggested a two-channel photometric restoration method in which the points are represented as functions in one channel and the background, constrained to be smooth by an additional entropy constraint, in the other. ... In the new CPLUCY implementation the stars can be at arbitrary x , y sub-pixel positions but the entropy constraint on the background, used by PLUCY, is retained. ...

551. stecf.nictools - NICMOS GRISM Tools
... The stecf.nictools package http://www.stecf.org/instruments/nicmos/nictools/ is a collection of IRAF cl scripts to group, process and co-add NICMOS direct and grism images. It was written to help the processing of NICMOS grism images after they have been calibrated with the STScI pipeline calnica and before spectra are extracted with the ST-ECF software NICMOSlook or calnicc . It is also useful for simple co-adding (shift and add) of direct images. ... 2000-05-10 ...

552. stecf.slitless - a Slitless Spectroscopy Quick-look Tool
Next: stecf.impol - an IRAF Up: The ``stecf" IRAF Layered Previous: stecf.nictools - NICMOS GRISM . Slitless is an IRAF task originally written to allow the ``quicklook" extraction of spectra from STIS direct/grism HST image pairs. ... Optionally, a Data Quality image extension can be used to avoid extracting flagged pixels. Slitless is configured to work primarily with the STIS G750L grism mode, but more modes can be defined by the user using a simple grism dispersion configuration file. ...

554. stecf.impol - Features
Next: stecf.impol - Package Tasks Up: stecf.impol - an IRAF Previous: stecf.impol - an IRAF . All the instrumental set-up, such as filters, polarizers, rotation angles, etc. are read from the image headers. Many input images ( 3 < N < 64) can be processed. ... Output images can be rebinned to increase the polarization signal-to-noise per output pixel. ... Output error images have fully propagated statistical errors from the input error images. ...
