The influence of small bipolar magnetic regions on basic solar quantities

Open Access

Table 1.

Different BMR populations considered in this work.

Population	Abbreviation	Magnetic flux
		range [Mx]
Ephemeral regions, H93	ERs	3 × 10¹⁸ − 4 × 10²⁰
Active regions, H93	ARs	4 × 10²⁰ − 1 × 10²³
All modelled regions	AMR	2 × 10²⁰ − 1 × 10²³
Large magnetic regions	LMR	3 × 10²¹ − 1 × 10²³^(a)
Small magnetic regions	SMR	2 × 10²⁰ − 3 × 10²¹^(b)
Small scale emergences	SSEs	1 × 10¹⁶ − 2 × 10²⁰

Notes. H93 refers to the definition used by Harvey (1993), on whose observations we rely.

^(a)

This also roughly corresponds to the smallest regions included in RGO/SOON sunspot group record.

^(b)

This includes small ARs and the largest ERs.
