N.P.G.S. LIBRARY PROGRAM. COMPUTESt FOR TWO SIMULTANEOUS TIME SERIES. 

 CROSS SPECTRA, POWER SPECTRA, PHASE AND COHERENCE. SUBPROGRAMS OBTAIN 

 THE FILTERED SERIES, REMOVE THE TREND, AND COMPUTE THE AUTO- AND CROSS 

 CORRELATIONS. THESIS BY JOHN G. MCMILLAN (JUNE 1968) USES DIGITAL A- 

 NALYSIS BY PROGRAM BLACKY IN THE STUDY OF TEMPERATURE FLUCTUATIONS 

 NEAR THE AIR-SEA INTERFACE, THE WAVE FIELD AT THE SAME POINT, AND THE 

 DOWNSTREAM WIND VELOCITY.

USED IN THE ANALYSIS OF OCEAN WAVE RECORDS, WHICH GIVE THE FLUCTUATION 

 OF THE HYDROSTATIC PRESSURE AT A POINT UNDER THE SEA AS A FUNCTION OF 

 Time. divided into two programs-- AML problem 840-017C COMPUTES ONLY 

 THE AUTOCORRELATION AND SPECTRAL ESTIMATES FOR EACH SINGLE TiME SER- 

 IES, AML PROBLEM 840-157B COMPUTES, IN ADDITION, THE TWO CROsS-CORREL- 

 ATIONS, NAMELY, THE IN-PHASE SPECTRUM ( CO-SPECT RUM ) AND THE OUT-OF- 

 PHASE spectrum ( QUA-SPECTRUM) for the SIMULTANEOUS TIME RECORDS, ALSO 

 COMPUTES THE MEASURE OF COHERENCY OF THE SYSTEM. REF. AML REPORT 131
