Hello,
I was comparing data from MAS to my own extractions of u' u'' and had claude code plot all of what is in mas versus my data and all matches except for the fair rite materials which in mas seem scrambled wrong data for wrong material.
Example:
Search in core_materials.ndjson for: "frequency": 100000.0, "value": 1564.4
This gives:
{"type": "commercial", "name": "61", "family": "NiZn", "resistivity": [{"value": 1000000.0, "temperature": 25}], "remanence": [{"magneticFluxDensity": 0.108, "magneticField": 0, "temperature": 100.0}, {"magneticFluxDensity": 0.094, "magneticField": 0, "temperature": 25.0}], "coerciveForce": [{"magneticFluxDensity": 0, "magneticField": 70, "temperature": 100.0}, {"magneticFluxDensity": 0, "magneticField": 88, "temperature": 25.0}], "density": 4800.0, "curieTemperature": 300, "material": "ferrite", "materialComposition": "NiZn", "manufacturerInfo": {"name": "Fair-Rite", "datasheetUrl": "https://fair-rite.com/61-material-data-sheet/"}, "permeability": {"complex": {"real": [{"frequency": 10000.0, "value": 1582.5}, {"frequency": 100000.0, "value": 1564.4}, {"frequency": 300000.0, "value": 1570.5}, {"frequency": 500000.0, "value": 1603.4}, {"frequency": 1000000.0, "value": 1729.7}, {"frequency": 1040000.0, "value": 1724.7}, {"frequency": 1080000.0, "value": 1717.1}, {"frequency": 1130000.0, "value": 1705.8}, {"frequency": 1170000.0, "value": 1691.8}, {"frequency": 1220000.0, "value": 1672.1}, {"frequency": 1270000.0, "value": 1650.8}, {"frequency": 1320000.0, "value": 1627.0}, {"frequency": 1380000.0, "value": 1598.4}, {"frequency": 1430000.0, "value": 1569.8}, {"frequency": 1490000.0, "value": 1536.8}, {"frequency": 1550000.0, "value": 1502.9}, {"frequency": 1620000.0, "value": 1468.3}, {"frequency": 1680000.0, "value": 1431.4}, {"frequency": 1750000.0, "value": 1394.8}, {"frequency": 1820000.0, "value": 1357.2}, {"frequency": 1900000.0, "value": 1319.4}, {"frequency": 1970000.0, "value": 1281.0}, {"frequency": 2060000.0, "value": 1243.0}, {"frequency": 2140000.0, "value": 1204.0}, {"frequency": 2230000.0, "value": 1165.7},
This should have: 125 permability but have 1582u instead.
According to claude code all the Fair-Rite materials seem to be loaded from maybe the wrong dataset (all other data i compared for other manufacturer matched) so given the above checked error i dont think it is just hallucinations.
So up to all 22 Fair-Rite materials data is loaded from wrong source.
