hmi.rdubinserD_fd05

Data Series Class: Fitted flow parameters averaged over turning point depths
Creating Module: ~rick/src/ringfit/binuparams
Input Data: hmi.rdVfitsc_fd05

Data Processing Status

The series is regularly populated once every Carrington rotation, with a total of up to 785,376 records per rotation. As of 12 Sep 2025 the series was complete through CR 2297 (May 2010 – May. 2025). For the first full year of HMI data there are 10,426,344 records. There is no SUMS data storage associated with this series.

For current processing status of ring-diagram data, see the Ring-Diagram Status page.

See also the status report for the source fits.

Data Notes

The per-record information in the series consists of six indexing variables and nine data. The indexing variables are identical to those in e.g. hmi.rdVtrack_fd05, hmi.rdMAI_fd05, etc., i.e. Carrington time and location, plus the appropriate radial order. The data variables are:

Ux_N — The number of fits surviving weeding of egregious values and contributing to the Ux etc. values; if less than mincount (15 for this series), the associated values are unset (NaN).
Ux — The value of Ux at the midpoint between rmin and rmax from a linear fit of the Ux values with classical turning-point radius between the radial-order appropriate values of rmin and rmax, weighted by the inverse square of their formal uncertainties, against turning-point radius
D_Ux — The RMS of the weighted Ux values in the same range
dUxdRt — The best linear fit of the weighted Ux to the turning-point radius
Uy_N — The number of fits surviving weeding of egregious values and contributing to the Uy etc. values; if less than mincount (15 for this series), the associated values are unset (NaN).
Uy — The value of Uy at the midpoint between rmin and rmax from a linear fit of the Uy values with classical turning-point radius between the radial-order appropriate values of rmin and rmax, weighted by the inverse square of their formal uncertainties, against turning-point radius
D_Uy — The RMS of the weighted Uy values in the same range
dUydRt — The best linear fit of the weighted Uy to the turning-point radius
MidTime — The midpoint of the tracking interval from which the source values of Ux and Uy and mode coefficients order, degree, and frequency from hmi.rdVfitsc_fd05 were derived
