DRM 1.4 changesSPDO• A requirement for A eff /T sys of 2000 (1000) over 50-240MHz for the Aperture Arrays (from Memo 125)– Change from 70 to 50 MHz acknowledged and subject toanalysis (see TN)• Maximum baseline of 50 km (200) for AAs(although 200 remains justified for other reasons?)• AA station diameter of 35m (30m) and a total numberof >140 (>160)• Dish polarisation purity of 40dB now applies over theaccessible sky (rather than just zenith)• Cadence of pulsar timing observations is nowspecified
