... This is done by taking in all input files the extension whose name is specified by the maintable parameter (called 'merged extension' in what follows) and merging the columns into a single output extension of the same name. ... Its contents is taken from the CCDID keyword (and QUADRANT for EPIC PN). ... To propagate other column specific keywords, they must be specified manually via the extensionchecks , mainattributes , maxattributes and minattributes parameters (see above). ...

... As with previous HST instruments, the FITS header keywords in STIS data files store important information characterizing the observations and telemetry received during the observations and describe the post-observation processing of your dataset. ... Calibration information such as the calibration switches and reference files used by the pipeline and parameters derived from the calibration, such as image statistics, wavelength shifts. ... Time: 0.3 sec Number of imsets: 3 . ... Dark image correction...

... We now describe the input parameters to the self-calibration tasks. ... For selfcal , you need not perform source , dra , or ddec selection if you use the selradec option (see below). minants : The minimum number of antenna that must be present before the tasks will attempt to find a solution. ... and phase : This determines whether the self-calibration tasks solve for just phase ( options=phase , which is the default) or amplitude and phase solution ( options=amplitude ). mfs : . ...

Next: Pipeline Calibration for STIS . ... Previous: HST Paper Products: A New Way to Look at HST Data . ... This simplifies enormously the data reduction procedure and allows the user to interpret high-quality data correctly. ... This may result in confusion about basic instrumental parameters, the precision of the set-up, the amount and distribution of calibration frames which are required and finally the assumptions on which the data reduction procedure should rely. ...

Next: Echelle Reduction Method Up: No Title Previous: Example . This Chapter provides the basic information necessary to understand the echelle љ package implemented in MIDAS . ... Tutorial examples are available in the system (command TUTORIAL/ECHELLE ) and are also included in the Appendix so that users without previous experience in MIDAS could become familiar with the calibration procedures. ... The methods described here are generally sufficient to cover a wide range of echelle formats. ...
