SPOT: The Spitzer Planning Observations Tool is the Java software in which observers plan and implement their observational requests on Spitzer. Users download the application onto a host machine running UNIX, Windows, or Linux. For a given observing mode, SPOT allows users to specify targets and to select observational parameters from a menu-driven graphical user interface, and returns to the user estimates of observing time.

IRSKY : The primary IPAC software tool for viewing wide-angle images of the infrared sky. IRSKY is designed as an environment for astronomers to plan observations in the context of the known infrared sky, with emphasis on the distribution of infrared cirrus and on estimates of the IR background. It is available for use from any Internet host equipped with X/Windows, or a compatible equivalent.

Coordinate Conversion and Galactic Extinction Calculator: An easy-to-use coordinate transformation, precession, and position angle calculator. It is flexible enough to convert accurately between Besselian and Julian equinoxes, taking the epoch of observation into account when needed. A recently added feature of the coordinate calculator returns the foreground Galactic extinction at any input position.

Interferometer Observation Planning: getCal is an interferometric observation planning software suite: it and its constituent tools can be used to resolve common star names into standard catalog designations and astrometry; extract visibility calibrators from the Hipparcos catalog according to a variety of geometric, brightness, and astrophysical criteria; compute target zenith and delay accessibility; interface with the Simbad astronomical database, the PTI and KI sequencer GUIs, visibility calibration codes, and sky visualization software. getCal also has other uses, is extremely portable, can be autonomously driven over a list of sources, and can be accessed either from either the Unix command line or a (Perl/Tk) GUI. A web interface for getCal, gcWeb, is also available.
