# HISTORY:

#   Dec 17, 2010: - created from [mergeCTD+LADCP]

#   Dec 18, 2010: - made to work

#   Dec 19, 2010: - improved considerably

#   Dec 20, 2010: - onward

#                 - BUG: depth-binning was off by 1 bin?!

#                 - added binning correction for instrument tilt

#   Dec 21, 2010: - added -h (seafloor depth)

#   Dec 22, 2010: - BUG: had not applied soundspeed-correction to w

# 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

# 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)

#	- 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
