Figure 1: Composite record of total solar irradiance compiled from detailed cross-calibrations of various daily radiometeric measurements (solid line) and reconstructed daily TSI based on SPM data (filled circles, connected by the dotted curve when there are no data gaps) for 2055 individual days between 1992 and 2003, i.e. from near the maximum of cycle 22 to the declining phase of cycle 23 ( top panel). The middle and lower panels show enlargements of four shorter intervals at different activity levels. The times corresponding to these zoom-ins are marked in the top panel by the double headed arrows under the roman numerals.

	Figure 2: Modelled total solar irradiance based on SPM data vs. composite of measurements. The correlation coefficient, , is indicated. The solid diagonal line represents the expectation values for a perfect model fit, a regression (dashed line) is hardly distinguishable from it.

Figure 3: Difference between the reconstructed total solar irradiance based on SPM data and the composite measurements. Each dot represents a daily value, the bigger filled circles 10 day averages. The solid line indicates difference = 0 ( top panel). The middle and lower panels show the same enlargements of four shorter intervals at different activity levels as in Fig. 1. The times corresponding to these zoom-ins are marked in the top panel by the double headed arrows under the roman numerals. Each filled circle now represents a daily value.
