NISP has released an upgraded version of the data products generated by the improved farside helioseismic mapping pipeline (GONG Farside Maps), which utilizes full disk GONG Dopplergrams This upgradation incorporates substantial improvement to the pipeline, addressing long standing issues and implementing new strategies throughout the workflow. Several new data products are now available to better serve the broader community.
Data products from the previous pipeline (hereafter the
Legacy pipeline) will continue to be produced through the end of this calendar
year to support direct comparison. All products are accessible through the link
above as well as on the GONG data download page.
The figure below compares the seismic signatures of magnetic
activity on the far side of the Sun as computed using the Legacy pipeline (top
panel) and the upgraded pipeline (bottom panel). In the Legacy pipeline,
regions of strong magnetic field appear as dark areas. In contrast, the
upgraded pipeline provides more detailed information: the farside maps are
shown with a dark background, high magnetic field regions appear as bright
features, and the frontside magnetograms are displayed in grayscale. The identified
farside active regions and their probabilities of appearing on the East limb
are marked by circles in both versions of the pipeline.
