Comments
For several years the author has been concerned with time series data reduction of guided missile data derived from tracking, telemetry and static test instrumentation. The data, which is acquired from many sources and comes in a great variety of formats and coding systems, must commonly be manipulated in a number of general ways before the calculation of functions specific to guided missile analysis is possible. The costs of programming many special purpose data reduction programs and the development time consumed in preparing and checking out these programs have strongly indicated the need for independent, general-purpose computer program modules or subroutines for data reduction. The philosophy arrived at by the author, is almost identical with that described in a recent publication by Healy and Bogert, and in a note by Bennet, but these individual module specifications are concerned with continuous functions, whereas the referenced article deals with spectral analysis.
