7.22 Configure Ray Header Words (CFGHDR)
The processed data that are output by the PROC command may contain
optional header words that give additional information about each ray.
This command configures the set of words that makeup each header. There
are (up to) thirty two different choices of words or groups of words to
include, as indicated by the bit mask following the command. Setting a bit
requests that those words be included in the header, and be placed in the
order implied by the sequence of the bits. Leaving all bits clear will
suppress the header entirely; though this can also be done without
changing the configuration via the NHD (No-Headers) bit in SOPRM
Input #2.

- When the RVP900 is operating in dual PRF mode, bit zero of the
"start" TAG word is replaced with a flag indicating that the ray's PRF
was low (0) or high (1).
- When trigger blanking is enabled, bit zero of the "end" TAG word is
replaced with a flag indicating that the trigger was blanked (0) or
normal (1). Note that the data within a ray are considered to be invalid
if any of the pulses that were used to compute the ray were blanked.
Tag Four words containing two 32-Bit TAG samples, one from the
beginning and one from the end of the ray:
