Syntax

Scan and Sub-array selection specification is a single integer (INT) or a range of integers(N0$\sim$ N1). Scans and sub-arrays can also be selected via boolean expressions of the type "$>$ INT", "$>$ =INT", "$<$ INT" or "$<$ =INT"⁵.

Full expression is a comma-separated list of any of the above index specifications. E.g.

• scan=0,1,2,3 selects scan numbers 0, 1, 2 and 3
• scan=0$\sim$ 3 selects scans in the range [0,3]
• scan=0$\sim$ 3,4,5 selects scans in the range [0,3] and scans 4 and 5
• scan=$>$ 5 selects all scans greater than 5
• scan=$<$ 5 selects all scans less than 5
