HMI Ring Diagrams Data Product Descriptions |
Versions of creating module used to produce records in the data series:
Because the MAI is a linear fit at the target time of the several means of |Bz| at the sample times, it can potentially be negative, especially if all available values are on one side of the target time. This “feature” was addressed in Version 2.1, replacing a negative extrapolated or interpolated value at the target time with a simple mean. There are no records in this series with negative values of MAI.
The following records have been subsequently reprocessed and exist in multiple versions in the DRMS database:
