<comments>Corrected 2026-09-23; supersedes ThrustCurve.org simfile 5f4294d20002e900000003c4 (user, RockSim).
Data of ThrustCurve simfile 5f4294d20002e9000000006d (RASP/cert) for this motor, converted to RockSim format; it replaces a curve that was wrong (see the audit). Thrust scaled to the certified 2464.6 Ns so the curve stays in its impulse class (the cert file integrates to class L).
