                  SOFTWARE SCIENTIST - PRINCETON UNIVERSITY


The Department of Astrophysical Sciences, Princeton University, expects to
have one or more positions to begin June-September 1998 in software 
development for the reduction and analysis of CCD photometric data
obtained by the Sloan Digital Sky Survey.  The SDSS, expected to begin
taking photometric data in Spring 1988, is a major project to obtain
five-color digital photometric data to 23m and galaxy and quasar spectra
and redshifts of some 1.1 million galaxies and quasars to 18m - 19m.  We
will carry out development work in areas such as: efficient algorithms
for object measurement; quality analysis; merging CCD frames; co-addition
of images from multiple passes across the sky; and automated searches for
variable objects.

The tasks include algorithm development; writing robust, efficient code 
(primarily on Unix platforms in C); and maintaining pipeline code.  We seek
individuals with a strong background in astronomical analysis and research, and
in algorithm development.  Experience in TCL, C++ and software engineering
practises is desirable.  There is likely to be some travel to the telescope
site in New Mexico and to other member institutions of the SDSS collaboration.
The appointment(s) will be made to the scientific or technical staff at a
level and salary commensurate with experience, for an initial period
of one year which can be renewed, depending on satisfactory performance and the
availability of funding.

Please send Vita, list of publications, detailed description of relevant
software experience, and arrange for three letters of recommendation to:

Jill Knapp
Department of Astrophysical Sciences
Princeton University
Princeton, NJ 08544

Consideration of applicants will begin on or about Mar 1 1998 and continue 
until the position is filled (this will be announced on the Website below).
This position is advertised subject to the availability of funds.
