WebApr 28, 2003 · ABSTRACT. We have measured the radial velocities of five 51 Peg–type stars and one star known to be constant in velocity. Our measurements, on 20 Å centered at 3947 Å, were conventional, using Th/Ar comparison spectra taken every 20 or 40 minutes between the stellar exposures. Existing IRAF routines were used for the reduction. WebN2 - We have measured the radial velocities of five 51 Peg-type stars and one star known to be constant in velocity.

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:
