PROFIT: A Tool for Visualizing and Modeling High-Resolution Spectra
PurposeProfit is a GUI (graphical user interface) tool for accessing high-resolution spectra. Profit displays spectra in various formats, allowing users to identify emission lines, to convert an identified line into velocity units using a user-selected wavelength, to store (and restore) individual spectra, to fit lines to gaussians, and other features. Profit primarily handles the "exploratory" phase of analysis, although it has some powerful features. Combining the velocity function with the ability to store and plot multiple features, it is very easy to see if lines from a particular ion or isosequence are systematically red- or blue- shifted, asymmetrical, or broadened. Profit's GUI is based on ROOT, a multifunctional library developed at CERN for high energy physics analysis. ROOT was chosen because it is well-supported and designed to handle histogram data smoothly. Although ROOT features and functions are used " behind the scenes " in Profit, the user does not need to have any familiarity with ROOT to use Profit. Profit runs natively on a variety of systems, including Linux, Mac OS X, Windows, and Solaris.
