Abstract
We correct minor errors in four equations in our recent paper [Biomed. Opt. Express 4(9), 1610–1617 (2013)]. They are equations (11), (14), (15), and (17) therein, where a factorial ratio was mistakenly omitted. All the other equations and analysis in the paper were correct.

We correct a factor that was mistakenly omitted in four equations in our recent paper [1]. They are Eqs. (11), (14), (15), and (17) in [1]. The correct versions of these four equations respectively are,
These equations were correctly given in our earlier paper [2]; they are equations (16)–(18) in [2]. Note also that cosβ is sometimes denoted by b. All the other equations and analysis in [1] were correct and are unaffected by this correction.References and links
