Appendix A. CRBasic Programming Instructions CovSpa Computes the spatial covariance of sets of data. Syntax CovSpa(Dest, NumOfCov, SizeOfSets, CoreArray, DatArray) FFTSpa Performs a Fast Fourier Transform on a time series of measurements. Syntax FFTSpa(Dest, N, Source, Tau, Units, Option) MaxSpa Finds the maximum value in an array. Syntax MaxSpa(Dest, Swath, Source) MinSpa Finds the minimum value in an array. Syntax MinSpa(Dest, Swath, Source) RMSSpa Computes the RMS (root mean square) value of an array. Syntax RMSSpa(Dest, Swath, Source) SortSpa Sorts the elements of an array in ascending order. Syntax SortSpa(Dest, Swath, Source) StdDevSpa Used to find the standard deviation of an array. Syntax StdDevSpa(Dest, Swath, Source) A.6.10 Other Functions AddPrecise Used in conjunction with MovePrecise, allows high‐precision totalizing of variables or manipulation of high‐precision variables. Syntax AddPrecise(PrecisionVariable, X) AvgRun Stores a running average of a measurement. Syntax AvgRun(Dest, Reps, Source, Number) Note AvgRun() should not be inserted within a For / Next construct with the Source and Dest parameters indexed and Reps set to 1. In essence this would be performing a single running average, using the values of the different elements of the array, instead of performing an independent running average on each element 503
