!      150129%20Deferment%20Levels.xlsx
! ------------------------------------------------------------------------------
! Device TYPE attributes have been prefixed by a 2-character deferment
! indicator. If the first character of a device's TYPE attribute is not "@" (or
! if a device has no defined TYPE attribute), the device is baseline. If the
! first character of a device's TYPE attribute is "@", the device is deferred.
! The level of deferral is indicated by the second character of the TYPE
! attribute:
!
! TYPE="@0..." : level 0 (required for CD4-Threshold with >100 pC/bunch and
!                         50 kHz operation)
! TYPE="@1..." : level 1 (required to approach CD4-Objective, but limited to
!                         ~100 pC/bunch)
! TYPE="@2..." : level 2 (required to meet science objectives across parameter
!                         range)
! TYPE="@3..." : level 3 (component to improve tuning time)
! TYPE="@4..." : level 4 (space for future components that may be needed)
! TYPE="@5..." : level 5 (probably not needed ... leave space in beamline for
!                         future installation)
! TYPE="@9..." : level 9 (previously baseline (costed) ... removed but might
!                         return)
!
! The remaining characters of TYPE define the device's engineering type.
