| Abstract: |
A graphical tool is being developed for the analysis of imaging Fabry-Perot data within IRAF. Constructed using the IRAF GUI interface, the tool provides the user with an integrated approach to the visualization and analysis of three-dimensional Fabry-Perot data. The tool includes both image and spectral visualization features, to provide for interpreting the cube in either of the two common ways: as a stack of images or as a grid of spectra. The use of image frame markers provides a tight interaction between the two windows. FPTOOL provides a means for both visualizing and manipulating the large three-dimensional data structures produced by Fabry-Perot observations. The available analysis tools spread across the range of Fabry-Perot analysis requirements: from building cubes out of constituent unevenly sampled images, to cube arithmetic, to line profile fitting, sky subtraction, and velocity map creation. While the necessary automation exists for rapid spectral reduction of Fabry-Perot data, features such as spatial masking allow for more detailed analyses as well. FPTOOL demonstrates the power of the IRAF GUI interface and is an important step in an integrated approach to the Fabry-Perot data analysis problem. |
