Elimination of Redundancy in Telemetered Data 
.
A new procedure is proposed for estimation of the 
intensity h( . ) of a Poisson process, stationary or non-
stationary; it does not require an a priori probability 
space for h(.) and can be readily programmed for 
execution on a general-purpose digital computer. The 
technique makes reduction of the sampling rate pos-
sible without sacrificing significant information, there-
by eliminating the problem of redundancy in data 
transmission from counting experiments. The relia-
bility of the estimate of h(.) is expressed in terms of 
the confidence relative error and the confidence co-
efficient. 
To illustrate the technique's efficiency in reducing 
data redundancy, and its reliability in smoothing (or 
extraction of the regression curve) data from counting 
experiments, the technique is used for estimation of
the density of energetic electrons in the auroral zone 
during a magnetic storm.
