Phase 2 Proposal Instructions for Cycle 10

5.6 Exposure Number [Exposure_Number]

---

Exposure numbers provide a method for unique labeling of exposures within a visit. The line numbers must be positive, monotonically increasing (but not necessarily consecutive) unique integers; floating-point numbers are not allowed. The smallest exposure number permitted is 1, and the largest is 999.

Note that exposure numbers for coordinated parallels must be sequential; see 6.3Coordinated Parallels.
