hmi.rdMAI_fd15_reproc

Data Series Class: Local Helioseismology Activity Indices
Creating Module: maicalc
Input Data: hmi.M_45s

Data Processing Status

This series contains subsequently reprocessed records of the series hmi.rdMAI_fd15 which have been removed from the main table.

Versions of creating module used to produce records in the data series:

v 2.0 : CR 2126:360 – 2199:015
v 2.1 : CR 2096:255 – 2125:015, 2200:360 – 2228:105
v 2.2 : CR 2228:090 – 2234:015

Note that records created with Version 2.0 lack valid values for several keywords: Samples, MeanMu, MeanPA, and COMMENT. However, values for the first three of these were subsequently set by an independent module using the same algorithm, data, and parameters.

Because the MAI is a linear fit at the target time of the several means of |B_z| 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:

[2197][345–330] : 565 records, originally processed 2017.11.19–20, reprocessed 2017.12.17–18
[2202][285] : 284 records, originally processed 2018.05.21, reprocessed 2018.06.19
[2202][210–195] : 568 records, originally processed 2018.05.21, reprocessed 2018.06.21–22
[2203][270] : 284 records, originally processed 2018.05.21, reprocessed 2018.06.27
[2204][270–225] : 1124 records, originally processed 2018.06.13–15, reprocessed 2018.07.07–11
[2214][345] : 284 records, originally processed 2019.02.27, reprocessed 2019.02.28
[2226][180] : 284 records, originally processed 2020.02.01, reprocessed 2020.02.03
