Ring-diagram analysis with GONG++
Résumé
Images from the updated GONG network (GONG+) have been produced since July 2001. In order to treat individual site images and the merged images (Toner et al., 2003) for local helioseismology studies, we have developed an enhanced tracking/remapping code that is now part of the new GONG pipeline (GONG ++) (Hill et al., 2003). We present here the data-cube, 3D power spectra and sub-surface flow maps that will become part of the new GONG++ products and comapare the preliminary results with the ring diagram analysis of MDI images for the same days.
