= Cut out of BitMask near HARP 1638 = The figure below shows a cut-out from the full disk active region mask approximately in the same location as the HARP bitmap shown at [[BitMap_HARP]]. The full disk map at hmi.Marmask_720s for this time is linked to the Mharp data series and can be exported via `lookdata`. Values in Marmask are 0 (off-limb), 1 (quiet Sun) or 2 (active pixels). The pixels in Marmask are not grouped into HARPs. [[http://sun.stanford.edu/~todd/jsoc-wiki/Mask.20120509_1000.png]] ----- Return to [[HARPDataSeries]]
