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 … WebRvidlines measures radial velocities from spectra by determining the wavelength shift in spectral lines relative to specified rest wavelengths. The basic usage consists of identifying one or more spectral lines (also called features), entering the rest wavelengths, and computing the average wavelength shift converted to a radial velocity.
WebN2 - 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. Webon other things. IRAF was ported to Solaris and a new version of IRAF, V2.10.3BETA, was released. The IRAF network information services, while a back-burnerproject for us, are continuing to evolve. This is getting to be quite a useful facility—check it out if …
