... Omgsource is an interactive SAS task which enables the user to reprocess an OSW rotated grism-image produced by the SAS task omgchain . ... The task allows the user to interactively select spectra from the input image: the width and height of the central spectrum extraction region, the widths and offsets (from the central extraction region) of the two background regions (one either side of the central region) can be varied. ... The spectrum plot file is produced using the SAS task omgrismplot . ...

... Apache HTTP Server Version 2.4 . ... Replaces the original client IP address for the connection with the useragent IP address list presented by a proxies or a load balancer via the request headers. ... The module overrides the client IP address for the connection with the useragent IP address reported in the request header configured with the RemoteIPHeader directive. ... When multiple, comma delimited useragent IP addresses are listed in the header value, they are processed in Right-to-Left order. ...

... Up: Data Analysis and Processing Techniques . ... Also, a method for quality control of CCD observations is suggested. ... Everyone who observes a celestial object using a CCD detects moving celestial objects as a ``by product''. ... We hope that our investigations may be useful for near-Earth space control and also for searches of the moving celestial objects through analysis of old and new CCD frames obtained at any amateur or professional astronomical observatory. ...

Examples of pipeline processing . ... This page presents examples of "on the fly" processing of FITS astronomical data available on the WEB using the HyperLeda pipeline tools. ... In many cases, raw data are archived and a consisten description of the file (FITS header) allows to process them on the fly. ... This first command makes a "pre-view" display of the image. o=fa:L93111HP1/00147&z=vg . ... The result of a pipeline processing is a FITS file that you can read as a normal disk file. ...

To run a process in the background as a job and carry on working add an (ampersand) at the end of the command line. ... The shell forks a child process to run the command and displays the job number ( [ n ] ) and the PID (Process IDentifier) number. ... If the command is likely to produce error messages you will need to redirect standard error. ... Do not run an interactive command that requires you to type something at the terminal as a background job. ... You will then have to kill its process . ...

... The analysis and reduction of the STIS flanking fields proceeded in similar fashion as for the imaging of the Main STIS Field. ... The DARK calibration reference file used in the CALSTIS data reduction steps was constructed using a 'delta-dark' image appropriate for the epoch of the flanking field observations. ... DRIZZLE drop-size used for the flanking fields was a "pixfrac" of 0.8. ... For information on the data reduction, please read first the technical information for the Main WFPC2 Field . ...
