Table 2. Parameters for the combined SnB/sieve procedure.
Parameter | SnB alone | SnB with sieving |
---|---|---|
Total reflections (phases) | 10N | 10N |
Triplets | 100N | 100N |
Peaks to select | N | N |
SnB cycles | 0.5N | 0.1N |
Number of sieve phases (NSP) | NA | 1.5N–4N† |
Sieve phase reduction (SPR) | NA | 0.15N |
Minimum number of sieve phases (NSPmin) | NA | 0.5N |
The initial set of sieve reflections is chosen utilizing a binary search for the first instance of non-origin degrees of freedom, as described in §5 of Smith et al. (2007 ▶).
