What is WITS?
The Web Infrared Tool Shed is a collection of web pages and programs ("tool boxes") for the analysis of astronomical objects that emit primarily in the wavelength range 2 µm to 1 mm. The goal of WITS is to provide the astronomical community with a uniform set of models over a large parameter space of source properties. WITS consists of:
And don't forget our motto:
- PDR Toolbox (PDRT) - plots of physical parameters (surface temperature, gas density, incident radiation field) as a function of observable spectral line intensities and ratios for standard model photodissociation regions (PDRs); and interactive fitting of observables to models.
- Dust InfraRed Toolbox (DIRT) - a comprehensive Java applet for modelling astrophysical process in circumstellar dust shells around young and evolved stars.

The development of these tools was supported by NASA Applied Information Systems Research Program grant NAG 5-10751 under the direction of Drs. Mark Wolfire, Marc Pound, Peter Teuben, Lee Mundy, and Steve Lord. Previous support was from NASA Astrophysics Data Program grant NAG 5-675.
