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 They are doomed to be always "out of date" since s/w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.
