Table 2.
TSI values during solar minima from the comparison of 
and TSI. The uncertainty presented is the standard deviation of the 3–4 determinations and is only a measure of the differences between the records. ERBS corr and VIRGO records cover two minima, which allow the comparison of the overall trends from Table 1 with the change between the observed minima.
