Sometimes when I work with the WWZ analysis it gives me an error, which says "java.lang.IllegalArgumentException: A positive range length is required" then it says the range is from the value I set to the minimum frequency, to the value I set to the minimum frequency (so the same value), even though I set different values for the minimum and maximum. I can't figure out what causes the error, I've tried changing each of the inputs individually to see what causes it and I'm still not sure. Can anyone explain what the source of this issue is?

Please provide example

To reproduce this, we need a few things:

  1. A data file or an AID object name and JD range
  2. Which series is being analysed (Visual, V, ...)
  3. The WWZ parameter dialog values with min/max frequency, frequency step, decay, time divisions

This may relate to a known bug or it could be something we don't know about.
