  We briefly explain the structure of the
Hartree-Fock-Bardeen-Cooper-Schrieffer (HFBCS) and Quasi-particle Random Phase
Approximation (QRPA) code hfbcs-qrpa, highlighting only the differences with
the code skyrme_rpa that has been previously published [G. Col\`o, L. Cao, N.
Van Giai, and L. Capelli, Comp. Phys. Comm. 184, 142 (2013)]. The code deals
with open shell spherical systems and non-spin flip, non-charge-exchange and
natural parity $(-1)^l$ excitations.
