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.

WebAbstract XCSAO is a software package for obtaining radial velocities of stars and galaxies from optical spectra using the cross-correlation method. It has been written to work within the IRAF environment, and is compatible with other packages being developed at SAO for optical spectra. WebFormation properties near a borehole are frequently altered by mechanical damage from drilling, leading to variations of formation elastic velocities in the radial direction. Inversions of the radial shear profiles are necessary for the real-time evaluation of the drilling conditions. In this study, we investigate acoustic wave propagation in a logging-while … WebThe pipeline takes advantage of existing IRAF routines and other readily available software so as to be simple to maintain, testable, and reliable. A radial velocity and stellar atmospheric parameter estimator code is also presented, which is used for further data analysis and yields a useful verification of the reduction quality. maytag washer control locked light on

"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: " - Iraf radial velocity
