Table 1
Parameters for each coefficient as resulting from multivariable linear regression analysis in the four tests (PH are planet hosts and CS are the comparison stars).

Notes. The offset is only included in the fit for planet hosts since the offset for comparison stars is by definition 0. The last column reflects the siginificance of the offset found between both samples.
