CDN-367: The Fornax External-Field Sweep

CDN-367 extends the Fornax dSph Jeans dispersion test by making the external field an explicit falsification parameter. Using the same Walker et al. member-star velocity bins and McConnachie Fornax structural inputs as CDN-366, this release applies the locked GCFT interpolation law ν(x)=1+1/(exp(sqrt(x))-1) through a scalar external-field proxy, x_eff=sqrt(g_N²+g_ext²)/a0. The artifact reports the preferred GCFT external-field strength, the Milky-Way proxy value, fixed-eta and grid-relieved fits, comparison to simple MOND, prediction hashes, figures, CSV tables, scripts, and validation notes.

Abstract

CDN-367 extends the Fornax dSph Jeans dispersion test by making the external field an explicit falsification parameter. Using the same Walker et al. member-star velocity bins and McConnachie Fornax structural inputs as CDN-366, this release applies the locked GCFT interpolation law ν(x)=1+1/(exp(sqrt(x))-1) through a scalar external-field proxy, x_eff=sqrt(g_N²+g_ext²)/a0. The artifact reports the preferred GCFT external-field strength, the Milky-Way proxy value, fixed-eta and grid-relieved fits, comparison to simple MOND, prediction hashes, figures, CSV tables, scripts, and validation notes.
