Number of discoveries N_disc	$21_{- 0}^{+ 2}$ $21_{ - 0}^{ + 2}$	$2_{- 0}^{+ 0}$ $2_{ - 0}^{ + 0}$

Notes. The column NP refers to ‘normal pulsars’ and the column SP to ‘slow pulsars’. Frequency-dependent parameters are determined for two frequencies: 58 MHz corresponding to the central frequency of the NPBS and 135 MHz for the central frequency of the LOTAAS survey.
