Observable series whose names appear in Red do not yet exist, or have not been populated. Those whose names appear in Orange have not been fully populated. Those whose names appear in Green have known correctable problems with certain records (unrelated to the data). These series were ingested into JSOC using a module called ingest_dsds_to_drms.c. The QUALITY keyword, which indicates the quality of the data, contains various bit flags. If top bit is set, 0x8000000, then no image is present. Otherwise, see the following links for the magnetic field, continuum intensity, Doppler velocity, and limb figure QUALITY definitions.
