mrv1z: Month Legendre Coefficient Table


One-month time series (mrvmt) are merged into 3-month sets, centered on the second month. The time series are then transformed into the frequency domain using PSERIES. This creates power spectra, which are subsequently run through PEAKFIND, to find the mode frequencies. These are stored as STSDAS tables, which are then processed using PKWORKS, which weeds out leaks and bad fits using the rejection criteria outlined in the sample table provided. PKWORKS uses these files to construct a-coefficient tables, such as the mrv1y, mrv1z and mrv1j data products. The mrv1z files are a set of Legendre rotation coefficients for each [n,l] combination where there is sufficient good data. The relationship between the mode frequencies (mrv1f files) and Legendre coefficients (mrv1z files) is illustrated below:
