# HISTORY END
# CTD REQUIREMENTS
# - elapsed elapsed seconds; see note below
# - depth
# - ss sound speed
# - w[_CTD] ddepth/dt
# - w_winch OPTIONAL; winch-speed estimate
# - temp OPTIONAL; used for backscatter calculation
# - %lat/%lon OPTIONAL
# - %CTD_transmission_errors OPTIONAL; if defined, -l is implicitly enabled
# OUTPUT PITCH
# - gimbal pitch is used
# OUTPUT EQUIVALENCES:
# 1) list -Q %uc_w.var UL/042.wprof
# list dc_w='$dc_w-%dc_w.mu' UL/042.wprof | avg -Qm dc_w
# 2-BEAM SOLUTIONS
# - both for beam- and Earth-coordinate data, two separate two-beam
# solutions (w12 & w34) are calculated:
# - w12 corresponds to ROLL axis (plotted with dashed lines)
# - w34 corresponds to PITCH axis (plotted with dotted lines)
# - the 2-beam solutions are largely independent of each other
# => key for detecting data problems, such as package wakes
# NUMERICAL OPTIONS
# - the first option in the list cannot be numerical!
# - if need be, use -v 1 as a dummy option
# ELAPSED TIMES
# - there are 2 different elapsed times used in this program:
# 1) elapsed based on firstgoodens in the LADCP time series
# 2) CTD elapsed time
# - CTD elapsed time does not have to start with zero!
# - do not use the Seabird elapsed field, which is only reported to
# 3 significant digits, causing significant jitter in dt; however,
# at least up to 2010 Seabird simply calculates elapsed time by
# assuming a 24Hz sampling rate and no record drop; therefore,
# it is best to calculate elapsed time as %RECNO/24
# - the elapsed field of the output is the elapsed time from the CTD
# file; this is required in order to be able to compare the times
# from the uplooker and downlooker-derived vertical velocity
# profiles
# - the .TL files use the LADCP elapsed time in output; as a result,
# the DL/UL .TL files have different time axes!
# - as a result, a profile only starts with elapsed==0 if the CTD
# is turned on when the LADCP is already in the water
# BINNED-PROFILE OUTPUT NOTES
# - residuals are calculated with respect to down-/upcast medians
# - w12 and w34 2-beam solutions are reported without considering
# -k (min samples)
# - elapsed times:
# - {dc,uc}_elapsed are averages estimated BEFORE
# - equivalence, assuming -o 10:
# 1) 004DL.prof dc_w depth
# 2) bindata -Sdowncast:1 -Fw.median,depth -n 20 depth 10 004DL.w
# VELOCITY AMBIGUITY ERRORS
# - quite extensive tests with DIMES US2 station 146, which has a lot of
# ambiguity velocity errors, reveal that $w_max_lim catches those errors
# quite nicely
# - even when the errors are not filtered with $w_max_lim, they do not
# affect the w profiles, as long as the median bin values are used
