DMF Engine – SPARC Error Analysis

Percentage error between required and modelled dark matter fraction for each galaxy and each radial zone.

1. Global Performance (Mean Absolute Error) Export CSV dataset

The cards below summarize the mean absolute error between the required dark fraction from SPARC and the DMF model, averaged over all galaxies. Values are given in percent.

Mean |error|
Central region
7.26%
Signed bias: -4.90%
Mean |error|
Mid-disc
4.21%
Signed bias: -0.30%
Mean |error|
Outer disc
5.30%
Signed bias: 2.80%
Mean |error|
Whole disc
1.70%
Signed bias: -0.53%

“Central / mid / outer” refer to the three radial zones used in the DMF engine. “Whole disc” is the average error on the disc as a whole.

2. Per-Galaxy Error Table

The table below lists, for each SPARC galaxy, the number of points used and the signed error between the required and modelled dark fraction in each zone. All values are in percent.

Error = (model − required), expressed as a percentage of the required dark fraction in the corresponding zone. Positive values mean the DMF model overestimates the dark fraction; negative values mean it underestimates it.
