Notes. The table lists the active region number, the observation date, the heliographic position (X, Y) on the solar disk, the heliocentric angle α and parameter μ = cos α, and the absolute magnetic field strength Babs. The observed spectroscopic sequences are defined by the cycle time tcycle and the total number of cycles, which amount to the total time of the sequence. The temporally averaged Doppler velocities νlos are based on fit ranges of ±50 mÅ and ±25 mÅ around the Ti I 5713.9 Å line center. The total uncertainty (in brackets) includes systematic and statistic errors.
