Comparison of survey sensitivity and frequency coverage of various time-domain pulsar surveys (green) and wide-area continuum image-domain surveys (red) against distributions of pulsar flux density measurements from the pulsar catalogue (open circles). An example power-law spectrum S_ν ∝ ν^α with a = −1.6 ± 1.0 for S₁₄₄ = 0.9 mJy is shown for reference.
