dqpar stsdas.hst_calib.wfpc



dqpar -- Edit the parameter set to select Data Quality File (DQF) flags.




The `dqpar' parameters specify which data quality values are used to flag a "bad" pixel in a WF/PC or WFPC2 task. For example, when running the task wfixup, setting `rsbit = yes' means all input values that suffered Reed-Solomon errors are "bad" and the task will interpolate over these pixels.

Note that this is a pset, not an executable task; it defines a set of parameters used by other tasks. Invoking the pset by name runs `eparam' on the parameter set, allowing the user to modify the parameters. Alternatively, the parameters may be modified on the command line by specifying the pset name and parameter name. For example, the user can type "dqpar.rsbit=no" to ignore the Reed-Solomon error data flags. Parameters can also be edited by using `eparam' on the calling task (e.g., by typing "eparam wfixup"), in which case `dqpar' will appear as one of the task parameters; the `dqpar' parameters may then be edited by positioning the cursor on the line containing the pset name and typing ":e". After editing the pset parameters, type <Cntrl>-Z to return to the main task parameter menu.

This pset is identical to dqfpar except that there is no file extensions.
