Synopsis
#include <flint/acb_theta.h>void acb_theta_g2_sextic_chi5(acb_poly_t res, acb_t chi5, const acb_mat_t tau, slong prec)sourceSets chi5 to \chi_5(\tau) and res to \chi_{-2,6}(\tau) = \chi_{3,6}/\chi_5, the meromorphic form that corresponds to the binary sextic itself under the correspondence with covariants. The matrix \tau is reduced, the theta values are computed with acb_theta_jet_notransform, and the transformation law of Siegel modular forms is applied.
