Application Packages are recursively structured in subpackages and tasks. They can be divided into two classes: general system and basic dataprocessing utilities, and packages specific to astronomical data reduction and analysis. The tasks are dominatly written in SPP and CL. The system packages are located in the base package of IRAF and provide tools for the CL, useful operating system utilities, and basic scientific utilities, f.e. for image processing: WebThe redshift or space velocity in km/s is specified either as a number or as an image header keyword containing the velocity or redshift. If a number is given it applies to all the input spectra while an image header keyword may differ for each image.
