r664 r1040 44 44 It has been developed in the last nine months and has been released to 45 45 ATNF users. 46 ASAP v2.0 underwent a major re-design to support varying numbers of channels per IF (or Beam). It also allows much more flexible data selection via the <b>seletcor</b> object. 46 47 Currently, the package has only been tested on linux (debian) system, 47 48 other linux and OSX binaries are going to be avaliable soon. -
