In its original form, the Fortran VM code also required a manual, iterative approach, modifying the input values for each run until the results match those observed. WVM presents the user with various forms to collect input for the model. Parameter checks assure that physically realistic values are fed to the model. Along with descriptive text, links to references in the online literature, and interfaces with relevant online databases, WVM greatly simplifies the use of the VM and improves user understanding of the model and the physics of cometary comae. Development of WVM in FY1999 helped in securing an FY2000 award from the NASA AIS Program to develop additional web-based tools for astronomical research that nonspecialists can easily and reliably use.
