Results for the case of the quadratic potential with a step
As an illustration, in this page, we list the various results from BINGO for the case of the quadratic potential with a step. The model parameters correspond to those that lead to the best fit to the WMAP seven-year data [for details, see, D. K. Hazra, L. Sriramkumar and J. Martin, BINGO: A code for the efficient computation of the scalar bi-spectrum, JCAP 1305, 026, (2013)].
