What was recently accomplished

• Fixed memory leaks PulsarMon seems stable at
  this point
• We are measuring noise at 59.5 Hz. Noise is more
  closer to value at 59.6 (Crab emission freq.)
  than at the interpolation point used previously
  (noise was grossly overestimated)
• We have written code that uses a finer resolution
  for spectrum (1/60 of Hz) to come closer to
  actual noise at 59.6 Hz
• The code is running in test mode on fortress. We
  have a problem due to old version of dmt to get
  the right values of the PSD at low frequency.
  This is going to be fixed soon

What needs to be done next

• Implement FOM4 cumulative PSD over the time of
  current time.
• Fix the problem with visualization of ellipticity
  of known pulsar. Intermediate goal make HTML
  page with values (this can be easily done because
  I have code to do calculations and it works).
