Indel rates for coronavirus Spike protein domains

Domain	Naive	EM	MCMC
λ (Insertion rate)
GS1	0.105146	0.110403	0.110 ± 0.006
GS2	0.0514705	0.0527830	0.053 ± 0.006
μ (Deletion rate)
GS1	0.105219	0.110480	0.111 ± 0.006
GS2	0.0515080	0.0528216	0.053 ± 0.006

The same phylogenetic tree was used for both domains (Fig. 6). Key to domain names: GS1 is the 5′ domain of the SARS coronavirus Spike surface glycoprotein, while GS2 is the 3′ domain of the same protein.
