[11.21] Analysis of Spectral Line Data Cubes with IDL

A. M. Johnson (University of Virginia), J. G. Mangum (NRAO)

To aid in the extraction of the useful information from a three-dimensional observational data set, we have developed a set of IDL macros which extract linewidth information. These tools were developed to analyze any three-dimensional (RA, Dec, Velocity) data cube. In particular, these tools are being used to analyze the linewidth characteristics of a set of molecular spectral line images of Comet Hale-Bopp obtained with the NRAO 12 Meter Telescope in late March of 1997. These macros will in the future be supplemented with other IDL macros which will allow analysis of the spatial and spectral properties of the molecular spectral line emission from objects such as molecular clouds, evolved stars, and external galaxies.

This work was supported through the NSF Research Experience for Undergraduates (REU) program.
