List of the specific frequencies SN,UCD derived in Sect. 3, along with the total absolute magnitude of the host environments.

Environment SN,UCD MV,host MV,host,individual cw SN,GC

Centaurus 5.1  ±  1.7 –23.2 –23.2 0.38 7.3  ±  1.5*
Fornax 4.9  ±  1.7 –23.0 –22.6 0.54 5.1  ±  1.2**
Hydra 12.5  ±  4.3 –22.9 –22.5 0.58 12.5  ±  1.5***
HCG 90 1.3  ±  0.7 –22.4 –21.1 1.41
HCG 22 3.9  ±  1.6 –21.6 –21.1 1.41
Local Group 4.1  ±  1.5 –21.5 –21.0 1.5 1.8  ±  0.3****

Notes. MV,host includes the full galaxy light in the UCD survey area (see text). MV,host,individual gives the magnitude of the brightest galaxy in the environment, which defines the assumed width σ of the GCLF and hence the correction term cw. The last column gives the literature value for the GC specific frequency of the brightest cluster galaxy, where available.
