Atlas of Analytical Predictions for Flat Rotation Curves, No Free Parameters, Equation Under Testing. Part I:

**Abstract This dataset constitutes a growing, versioned Atlas of analytical predictions for the asymptotically flat rotation velocity of disk galaxies using only visible baryonic mass and observable photometric radius. The prediction uses the relation vc = sqrt(4 G M0 / R0) where M0 is the total visible mass, bulge plus disk plus gas, and R0 is the photometric radius where the system closes, defined as the last detectable isophote where the last star is seen. No dark halo, no free parameters and no tuning are introduced. Each version of this dataset adds one prediction sheet for a single galaxy with perfectly defined variables, satisfying Condition A for SA galaxies with regular isophotes or Condition B for SB galaxies with well defined bar plus disk. Each sheet reports M0, R0, vpred and the observed Vflat from public databases such as SPARC for direct comparison. The atlas is versioned to provide timestamped priority. v1 begins with NGC 7814. The underlying relation is under independent testing. The author invites independent blind verification using galaxies not included in this atlas.
