The GOLF signal acquisition was designed to integrate the solar signal during 4 s with a cadence of 5 s. This 5 s signal is triggered by the GOLF Local On Board Time (LOBT), which is driven by the SOHO OBT (On Board Time). This OBT is specified to always be within 20 ms of TAI (Temps Atomique International). However, the GOLF temporal sampling suffered some delays during its lifetime, either due to SOHO reconfigurations, or to operational events.

The scaled velocity data set provided by the GOLF team is corrected for these delays, modulo 10 seconds (the segments corresponding to the delays have been shifted by multiples of 10 s, the actual one-wing velocity sampling). Table 1 summarizes the timing issues. The first column is the date when the correspondence to TAI changed; the second is the TAI (in seconds) corresponding to the first block of the day (e.g. the first data block on April 11, 1996 is 00:00:30.0137 TAI); the third column is the delay compared to the first point on April 11, 1996 and the last column is the residual delay after making the correction in multiples of 10 s
