This was done by taking a strong, isolated line at 2.2814µm and using that as a reference point to all the remaining spectra. The procedure allowed for correcting in one step the intrinsic radial velocity and any zero-point offset that could remain from the wavelength calibration. reihill park irvinestown

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.
