Coefficient field
The coefficients anβ generate a number field of degree 19. It is generated by the eigenvalue Ξ± of T=T2β+T3β, whose minimal polynomial is

AtkinβLehner signs
For pβ₯N every form in the orbit has apβ=βpk/2β1wpβ. The Fricke sign is wNβ=+1, so the sign of the functional equation is (β1)k/2wNβ=β1: each L-function in the orbit has odd analytic rank.

Provenance
Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.261 s (one thread) and proven: the dimensions are certified, and the characteristic polynomial of T over Z is reconstructed by CRT past a rigorous coefficient bound.
The engine's checks
dim M^+ at levels [1, 97]: [1, 42] (certified at ell = 2147483137)T = [(2, 1), (3, 1)]; h of degree 40 = 1 x 40 (phi(ord eps) x dim S_k^new); 8 primes, 0 rejected
