  Much like the important work of Hardy and Ramanujan proving the asymptotic
formula for the partition function, Auluck and Wright gave similar formulas for
unimodal sequences. Following the circle method of Wright, we provide the
asymptotic expansion for unimodal sequences on a two-parameter family of mixed
congruence relations, with parts on one side up to the peak satisfying r (mod
m) and parts on the other side -r (mod m). Techniques used in the proofs
include Wright's circle method, modular transformations, and bounding of
complex integrals.
