Luminosity function for Type Ibc SNe. The figure shows the number of objects per absolute magnitude bin (M_r) for different sample selections. The black distribution is for the 129 SNe Ibc initially selected from the BTS explorer and using the absolute magnitudes from that site. This distribution has an average and standard deviation of M_g/r = −17.61 ± 0.72 mag. The blue dashed distribution is for the 94 SNe Ibc that is kept after additional quality cuts have been implemented. These magnitudes are measured using GP on forced photometry data and yield M_r = −17.64 ± 0.54 mag. The red distribution of the final 14 normal SNe Ibc has an average and standard deviation of M_r = −17.90 ± 0.73 mag. The vertical black dashed line marks the upper limit of M_r = −17.8 from Woosley et al. (2021).
