Notes. The errors are about 0.001 c/d and 0.7 mmag; the colon (:) denotes uncertain detections. A “+” in a frequency ID indicates that the frequency is the one with the highest amplitude in a group (Sect. 5.3, after pre-whitening for f4 +). As the example of f4 + shows, such frequencies may not be constant with time (Sect. 5.1 and Paper II).
