Periodicities in PSP/FIELDS HFR radio power, AIA emission in Region 2 (as defined in Fig. 3), and HMI intensity. (a) 6.225 MHz and (b) 18.375 MHz interpolated normalized power with black dots indicating the identified peaks; (c) periods identified for all frequencies >5 MHz; (d) AIA 171 Å and (e) 211 Å detrended normalized intensity with black dots indicating the identified peaks; and (f) periods identified for all AIA passbands in Region 2, versus wavelength with temperature response curves overplotted; (g) and (h) HMI emission in two regions; and (i) periods identified in HMI data. Panels d and e: AIA lightcurves have been detrended. The units are residual data numbers (DNs) after a 10-minute average curve was subtracted. Panel f: temperatures of the data points are those listed in Table 1 of Lemen et al. (2012) for each passband (these are approximately the peaks of the temperature responses), but the colored lines show the temperature responses themselves, in arbitrary units, to give a better representation of possible temperatures for each data point. When more than one temperature is listed in Table 1 of Lemen et al. (2012), we have included a data point for both, since we cannot distinguish them.
