Occurrence rates of planets in the HADES sample.

Period
m_p sin i (M_⊕)	[1,10]	[d] [10,10²]	[10²,10³]	[10³, 3 × 10³]
[10²,10³]	k_p = 0	k_p = 0	k_p = 0	k_p = 0
−	n = 56.0	n = 55.8	n = 54.4	n = 51.7
−	f_occ < 0.02	f_occ < 0.02	f_occ < 0.02	f_occ < 0.02
[10,10²]	k_p = 0	k_p = 1	k_p = 0	k_p = 0
−	n = 55.0	n = 49.3	n = 33.2	n = 14.9
−	f_occ < 0.02		f_occ < 0.04	f_occ < 0.08
[1,10]	k_p = 3	k_p = 7	k_p = 0	k_p = 0
−	n = 29.0	n = 8.2	n = 0.7	n = 0.4
−			f_occ < 1.65	f_occ < 2.70

Notes. k_p and n are the number of detected planets and of stars sensitive to planets in the parameter space interval, respectively, and f_occ is the planetary occurrence rate, computed as average number of planets per star.
