Abstract

The Sloan Digital Sky Survey (SDSS) is an astrophysics experiment to take 20-30 Terabytes of imaging data and spectroscopic data to map one half of the northern galactic hemisphere. The survey will utilize a dedicated 2.5 meter telescope at the Apache Point Observatory in New Mexico. SDSS collaborators include the Fermi National Accelerator Laboratory, the Institute for Advanced Study, The Japan Promotion Group, The Johns Hopkins University, Princeton University, the United States Naval Observatory, the University of Chicago, and the University of Washington. One of the key offline software components of SDSS, is dervish (Survey Human Interface and Visualization Application). Dervish is a collection of routines and executables useful in the offline analysis of astrometric data. The dervish software integrates code developed by the collaboration with other software products developed from independent institutions. The products that comprise dervish are:
        dervish		Astrometric data analysis software. Top-level component.
			Origin:  Fermilab/SDSS collaboration.

	sdsstools	Common utility scripts and tools for SDSS software.
			Origin:  Fermilab/SDSS collaboration.

	fsao		Fermi-modified SAOImage standard display program
			for greyscale images.
			Origin:  Smithsonian Astrophysical Observatory.

	tcl/tk		Command line interpreter tool (Tcl) and GUI 
			toolkit (tk).  Product structure was re-arranged to 
			fit in Fermi product environment.
			Origin:  John Ousterhout (University of California at 
			         Berkeley).

	tclX		Extended Tcl.  Product structure was re-arranged to
			fit in Fermi product environment.
			Origin:  Karl Lehenbauer (NeoSoft) and Mark Diekhans.

	ftcl/ftk	Fermi enhancements to ftcl and ftk.
			Origin:  Fermilab.

	fpgplot		Fermi enhancements to pgplot.
			Origin:  Fermilab.

	pgplot		Plotting package for drawing simple scientific
			graphs on various graphics display devices.  Product 
			structure was re-arranged to fit in Fermi product 
			environment and several routines were added.
			Origin:  Caltech Astronomy Department.

	libfits		FITS I/O routine package.  Product structure was 
			re-arranged to fit in Fermi product environment and
			several routines were added.
			Origin:  Alan Uomoto (The Johns Hopkins University).
