- I earned Bachelors (1973)
and Masters (1974) [thesis] degrees in
Planetary Science from
- After I got my SM degree, I took some enforced time off from astronomy
due to a lack of jobs and developed financial software in Boston at
Publishing Company in 1975 and 1976, while still doing some work
at MIT in my spare time (helping write
my first published paper).
- In 1976, I left to develop astronomical software full-time, in lieu
of graduate school, at
Cornell University in
Ithaca, New York from 1976
until 1979, soon
helping discover the Uranian rings and publishing
my second paper in Nature. More research and publication followed
through the 1979 move of my research group to M.I.T., where I worked until 1984.
- In 1984, I came to the
Smithsonian Astrophysical Observatory to work on the
Infrared Telescope (and helped write
this paper about its results). Along the way, I developed the graphics
terminal emulator for xterm.
I am in the list of contributors at the end of the xterm man page on any
X-Window supporting system.
Since that project was completed in 1990, I have worked at the
SAO Telescope Data Center,
developing and using software for
astrometry and the
of optical and near-infrared spectra and images. Besides a few more pipelines
for spectrographs, I have written the widely-used
RVSAO redshift computation package
WCSTools image world coordinate system, FITS file, and source catalog package.
