* The tape data at Kagoshima are in JST before 1992 and in UT after 1993.
* At ATH, the antenna was set near the building from February 26, 2012 to September 25, 2012, so that the data becomes highly noisy in this interval.
* At ATH, the spectral plots and spectral binary data were slightly incorrect up to August 12, 2013, because the lower byte of the binrary data was treated as signed integer. It should be treated as unsigned integer. This cause error up to 256 digit in 65536 digit (two-byte integer data).
