Hi Ted,

  It is easy to get long period period response from a short period
sensor. Just use my utility program, WQFilter.exe. It operates on PSN
Type 4 files, and can extend the useful period by a factor of 8 or
more. I operate medium period sensors, and I would be lost without
this program. See my web site at

for the program and explanatory pages. Be sure to follow my
recommendations on the optimal use of WQFilter.
