SDSS Primers

This area dervish/doc/int (or $INT_DIR) contains an introduction to SDSS software and some fits files. Each file is in a subdirectory that names its subject, along with some sample files.

The Primers

This is the suggested order for working through the files:
  • setup: code distribution
  • dervish: a quick romp through SDSS tools
  • tcl: tool command language; what you type to
  • pgplot: plotting tool; use the help tool; simple examples of compiling
  • help: how to read and write documentation
  • saodisplay: how to display images
  • rcvs: code management and control; how to get the latest.
  • regions: how to get at the pixels and related information "legally"
  • lists: linked lists of objects
  • histograms and arrays: how to create and plot them.
  • Where this is located

    To access the files used in the examples, use the variable $INT_DIR. It is set for you when you "setup dervish" and when you run dervish. Do the following to find these files: fndaub % setup dervish fndaub % cd $INT_DIR fndaub % ls -CF CVS/ help/ primers.html saodisplay/ style/ doc/ lists/ rcvs/ setup/ tcl/ fits/ pgplot/ regions/ dervish/ whoswho/ Read the hypertext version of this document by doing this: fndaub % setup www fndaub % setenv DISPLAY my_machine_name:0.0 fndaub % xmosaic primers.html & or by accessing it through the SDSS home page, under "Introduction to SDSS."

    The hardcopy is a postScript file, located in $DERVISH_DIR/doc/primers.ps.

    Acknowledgements

    Steve Kent and Robert Brunner supplied text that is incorporated into these primers. Many thanks to all who have read and commented on these primers. They are doomed to be always "out of date" since s/w development is dynamic. Thanks to all the programmers who are making this package work, and to all who help me keep these primers accurate.
