# edit RDI PD0 file, e.g. to replace pitch/roll/heading with external values
# NOTES:
#
# - editing instructions can be provided either in an editing file (primarily
# for ensemble-specific editing), or with the -x option on the command line
# (only or editing applied to all ensembles)
#
# - Data-Editing Library:
# p(<pitch>) set pitch value (RDI not gimbal pitch) of current ensemble
# r(<roll>) set roll alue value of current ensemble
# h(<heading>) set heading alue value of current ensemble
#
# swap_beams(<b1>,<b2>) swap data from beams b1 and b2
# input in beam coords required
# beam rotation is equivalent to 3 consecutive beam swaps
# basic BT data are swapped as well (not RL and not SIGNAL_STRENGTH)
#
# earth2beam() transform beam to earth coordinates
# does not handle bin-remapping
# input in beam coords required
#
# ensure_UL() overwrite transducer-orientation flag in data file
# ensure_DL()
#
# - -x notes:
# - multiple perl expressions can be combined with ,
#
# - Edit File Syntax:
# - # comments ignored
# - empty lines ignored
# - [space] <ensemble-number|*> <space> <perl-expr>
# - Examples:
# 162 p(3), r(4), h(3.14)
# HISTORY:
# Nov 25, 2013: - created
# Dec 18, 2015: - added switch_beams()
# - added -x
# Jan 9, 2016: - renamed switch_beams() to swap_beams()
# - wrote documentation
# - change output data-source ID from 0x7F to 0xE0
# - updated getopts to current perl version
# - adapted to [ADCP_tools_lib.pl]
# Feb 15, 2016: - added ensure_UL() ensure_DL()
# Feb 23, 2016: - added -k
# Feb 26, 2016: - added basic BT data to swap_beams()
