The Cohesion UFT Research Calculator, Version 6.1

Version 6.1 of the Cohesion UFT Research Calculator corrects two values in thegalactic-scale modules of Version 6 [1]. Both were flagged by the machine audit of theseries corpus and both are settled here by recomputation from the publishedformulas. First, the density ratio at the MOND transition is Dtrans/DGUT = 0.439, not16.79: the Dgal paper [2] prints the correct inversion of the exact R(Dst) solution [3]but evaluated it with the factor (1+2R4) misplaced. The corrected value is confirmedindependently by monotonicity, since R = 1 at DGUT and R increases with D, so Rtrans= 0.748 must sit below DGUT. Second, the global suppression constant of therotation-curve law [4] carries the unit pc/(km/s)2, not kpc/(km/s)2: the paper's ownidentity β−1 = a0 is satisfied only by the parsec reading, which also matches thestandard scale a0 ≈ 3.7 (km/s)2/pc. Neither correction changes a0, Rtrans, or any otherderived constant; every SI value downstream of β was already computed from 1.38 ×10−10 m/s2. The corrected standalone calculator accompanies this paper. Thecorrections propagate to the Dgal paper, which takes an erratum, and to the site,which has been updated.
