Simulations of an active region located on the equator θ = 90° with a size of ASn = 1.6 × 10-3 relative to the stellar surface. The rotation period is 25 days and the inclination is 90°, yielding vsini = 2 km s-1. Left panels: simulated data for a Sun-like star (Teff = 5770 K) and ΔTspot = 310 K. Right panels: the same for a K0 star (Teff = 5000 K) and ΔTspot = 250 K. From top to bottom: photometric (in Johnson V-band), astrometric, RV, FWHM, BIS, and S index variations induced by the active region. The results with surrounding faculae (Q = 3) are shown with black solid lines and those without faculae (Q = 0) are plotted with black dashed lines. The same simulations made with SOAP 2.0 are plotted with red lines.
