Abstract

We study the properties of high-degree p-modes using ring diagram analyses. Ring diagrams produced from full-disc Doppler velocity, continuum and line-depth images of the Sun obtained by the Michelson Doppler Imager (MDI) are studied to check how mode characteristics such as asymmetry, line-width etc. vary with the type of observable used for producing the spectra. We have selected data from a low solar activity period to ensure that the activity-related effects do not influence our conclusions.
