PRESTO v2.1

New in Version 2.1:

• accelsearch now has a "jerk" search capability (thanks to UVA
  undergrad Bridget Andersen for help with this!). This makes
  searches take a lot longer, but definitely improves sensitivity
  when the observation duration is 5-15% of the duration of the orbital
  period. Typically -wmax should be set to 3-5x -zmax (and you probably
  never need to set -zmax to anything larger than 300).
• Ability to ignore bad channels on the command line (-ignorechan)
  (see rfifind_stats.py and weights_to_ignorechan.py)
• Lots of new python utilities (such as for handling RFI, showing
  bandpasses, making waterfall plots, ...)
• New wrappers for the python interface (will make the transition
  to Python 3.X much smoother later this year)
• Many bug fixes and minor improvements
