Image Display Paradigm #3 (IDP3) is an IDL package developed by the NICMOS Software Group at the University of Arizona. The original purpose was to provide a versatile graphics tool for PSF subtraction with NICMOS data. However, with a clever structured design IDP3 became a unique and very powerful image analysis tool. In this presentation we explore IDP3, its development and its features.
IDP3 is a tool for manipulating data images that employs a powerful but easy-to-use graphical user interface with support for FITS and HDF input formats. It allows the user to work with a collection of images and display one or more in a graphics window simultaneously. Images may be individually moved, scaled, and rotated to bring features into registration. Each image may be subtracted from, added to, or combined with the composite display using one of several other functions (divide, multiply, XOR, etc.). IDP3 provides a region-of-interest pop-up tool for intensive examination of sub_regions of the main display. There are cross-section plots, masks, surface plots, statistics, spreadsheet displays, radial profiles, and other tools at the user's disposal. Combination or individually registered images may be saved to FITS files.
