1, the correction value listed has been applied to the TIM data, and correction values that had been computed independently and which agreed well with the values in Table 3 have been applied to the VIRGO data for instruments PMO06V and DIARAD.

Representatives from each of four TSI instrument teams, TIM, ACRIM, DIARAD, and PMO6, would provide an instrument that has a design basically equivalent to their respective flight instrument(s).
It did not include TIM, ACRIM, or DIARAD. The TSI instalment (PMO6) was operated in air, rather than in vacuum.
