Welcome to the Web Infrared Tool Shed!

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 currently consists of:

• PDR Toolbox (PDRT) - plots of physical parameters (surface temperature, gas density, incident radiation field) as a function of observables (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.
  And don't forget our motto:
   "Reliable Astrophysics at Everyday Low, Low Prices!"^®

  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.
