Three-quarters of our sample of evolved, variable stars have periodic light curves. We characterize the stars in our sample using the multiple periods found in their frequency spectra. Additionally, we use single-epoch Two Micron All Sky Survey measurements to construct the average infrared light curves for different groups of these stars. File Summary:

Note (1): A "-99.0" indicates no data. Note (2): Where the reddening-free W magnitude is defined as: W=R-4(V-R). Note (3): Classification on the Fourier period-luminosity diagram as described in the paper: 1-4 = the object lies on Sequences 1-4, -1 = indicates Sequence E, -2 = indicates Sequence D, 9 = indicates that the star is identified with the One-Year Artifact, 0 = is a star outside the boundaries of any period-luminosity classification, -99 = we were unable to classify this star, most likely due to the lack of a Red light curve or a Ks magnitude.
