A talk at the American Museum of Natural History, April 13, 2015
Over the past 45 years, I've developed an interest in maps into
a variety of software which implements a variety of mapping functions
to translate between images, catalogs, and precise coordinates in space.
After several less portable programs, I wrote WCSTools, a user-friendly
suite of software to do all of those things, with a variety of other
tools added to manipulate files. To cover the third dimension, I added
the RVSAO package to IRAF to use various methods to compute radial
velocities and redshifts from spectra of astronomical objects, be they
asteroids, stars, or galaxies. I'll discuss the evolution of these
tools and the astronomical data environment.
