We have a number of technical papers on photo. These should probably be integrated with this document at some point.
This is a first draft, not a finished product. We intend to modify it as desired by readers (especially the JPG) who require more information on specific topics. Please send any comments or suggestions to Zeljko Ivezic, Robert Lupton, or Jill Knapp at Princeton. With your help, we can improve this document.
To run photo, you'll first have to acquire a standard SDSS environment,
and install all products required to run astrotools
(or
photo
if you don't want to build it yourself). You can
then say setup photo
and proceed to the next paragraph.
The TCL top-level routines to run the PSP is in
$PHOTO_DIR/etc/ps_pipeline.tclyou may want to use cvs to check out your own copy of photo. There's more code in
$PHOTO_DIR/etc/ps_pipeline_procs.tcl
and $PHOTO_DIR/etc/photo_procs.tcl
.
The frames pipeline routines are in the same place, but called
frames_pipeline.tcl
and frames_pipeline_procs.tcl
The main routines are called run_ps_pipeline
and
run_frames_pipeline
, and each
expects one argument, the name of the file
that gives the desired order of business, and the location of all
files required to run the postage stamp
or frames pipeline.
If you are familiar with emacs' TAGS files, you can profitably say
sdssmake tags
in $PHOTO_DIR
to make browsing
the source easier; tags are built for both C and TCL symbols.
