Definition of the radio visibility criteria for the surveys Molonglo 2, Green Bank 2, Green Bank 3, and Parkes 2. For each survey we show the pulsar selection, classification, and counting in the redefined survey coordinates region (Table 3), and the ratio between the pulsar fluxes and the threshold ones re-evaluated by taking into account the fudge factor defined in Table 3. The object categories listed in the legend are: ATNF (black cross): pulsars inside the new survey coordinates region defined in Table 3 that are listed in the ATNF catalogue; ATNF vis (blue dot): pulsars that are visible according to the new survey parameters listed in Tables 2 and 3 and/or listed in the ATNF catalogue; ATNF NaN (green dot): pulsars listed in the ATNF catalogue for which it is not possible to evaluate the threshold flux; Detected (red circle): pulsars that have been detected according to the new survey parameters listed in Tables 2 and 3.
