Hello Chris,
What is the purpose of posting events at the PSN  web page? Should we post
the raw data or an edited file? What should be the goal when filtering?
I am almost new in the list, a very ignorant one. Your comments on this
subject would be very appreciated.
Best regards,

      It would be great to know what posting you were referring to.

      There are two good reasons for going to very low frequencies:
      You may want to cut out man made noise.
      If you have severe wind / weather noise, you may need to reduce the
frequency      quite a bit further.
      Very long period responses are available. The Lamont-Doherty
Cooperative Seismographic Network (LCSN) springs to mind.
      Do these considerations apply?
