All possible patterns of error caused in corrected base-space sequence by a single
wrongly corrected error in the observed sequence of type +*d* (where *d*=1, *α*or *β*). The ‘Positions’ column indicates all possible pairs of positions at which an error
can occur and be wrongfully corrected; it is not necessary to identify which member
of the pair corresponds to which form of error as the resulting pattern is the same.
In all cases the error pattern should be multiplied element-wise by the error type
(*d*) to get the actual pattern (e.g. a wrongly corrected + *β*error at _{c2}results in an error pattern of 00*β*00).
