The in-beam angular distribution method has been extensively used for the measurement of important cross sections for the p process nucleosynthesis. However, transitions that are beyond the detection limit of each setup, as well as the contribution of the continuous part of the de-excitation spectrum are not considered in the analysis, which results in a missing yield on the final value of the measured cross section. In this work, an attempt to quantify this missing yield is presented using the FIFRELIN code. The corrected results are compared with results measured by the more accurate activation method.
