  2. Headlines • Mapping • Tracking • Background noise Tucson, 2008 January 29-30

  3. Old version vs. New version Precedent version • GONG images were the only standard inputs • Only the TC projection has been used • Tracking images. Ephemeris formula of the SSC • Cleaning power spectra. Backward difference turned off Recent version • The ringpipe is now adapted to the MDI data, no pre-processes of the MDI images are needed anymore. • Several projections are implemented, notably the Postel projection • Tracking images. What is the best way to estimate the SSC? • Cleaning power spectra. Removing the mean image. Tucson, 2008 January 29-30

  4. Old versions vs. New version Precedent version • GONG images were the only standard inputs • Only the TC projection has been used • Tracking images. Ephemeris formula of the SSC • Cleaning power spectra. Backward difference turned off Recent version • The ringpipeline in now adapted to the MDI data, no preprocesses of the MDI images are needed anymore. • Several projections are now implemented, notably the Postel projection. In progress: the latitude range precision will be extended from 0.5 deg to 7.5deg, so that any center of projection required by the pipeline user will generate a readable file name. • Tracking images. What is the best way to estimate the SSC? • Cleaning power spectra. Removing the mean image. Tucson, 2008 January 29-30

  7. black :gnomonic red :transverse cylindrical green: Postel full~0.6Mm dotted~ 6Mm dached~11Mm dashed-dotted~16Mm Averaged meridional flow over 14 days for 3 projection Tucson, 2008 January 29-30
