# TODO:

#	  detection so that editing stats make sense

#	- own seabed detection (P403)

#	- make upcast-flag valid for yoyo casts

#	- make diagnostic output 3-beam field work for Earth coordinates

#	- remove water-depth from BT code, which is not really used and a bit of an outlier

#	  because mean and stddev are used instead of median/mad

#	- read assumed ADCP soundspeed from data file, instead of assuming 1500m/s

#	? use instrument tilt in sidelobe editing?

$antsSummary = 'calculate vertical velocities from LADCP & CTD time series';

# HISTORY:

#				  - added binning correction for instrument tilt

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

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

#				  - removed beampair velocities from code

#	Dec 25, 2010: - adapted for surface-wave correction in terms of acceleration (CTD_w_t)

#				  - removed elapsed_mismatch

#				  - removed winch_w, wave_w

#	Dec 26, 2010: - made -p output layout independent of -x to avoid Makefile problems

#				  - folded-in backscatter calculation from shear method

#				  - folded-in BT calculation from shear method

#	Dec 31, 2010: - added weighted mean w profile to output

#	Jan  2, 2010: - BUG: BT_w.mad could bomb with division by 0

#				  - added -l

#				  - removed CTD headers from output

#	Jun 26, 2011: - added -u

#				  - changed package correction from acceleration to velocity, because of

#					Stan's Antarctic data set where accelerations are zero but package effects are

#					there

#	Jul  3, 2011: - replaced old package-velocity correction -x code by new beamvel correction

#						 or end with CTD in water

#				  - moved rarely used option -s to -k

#				  - added -s)kip <ens> option

#				  - had to very very slightly relax an assertion (by 1e-10 seconds...)

#	Aug  3, 2011: - added -z)ap to truncate range, based on Stan's 2009 data set (017-019 most clearly)

#				    obs that final 2 velocities are outliers; could be due to color bar, should check with

#					residuals

#				  - BUG: closed STDOUT caused problems with tee in plotting scripts

#				  - added %run_label

#				  - added PostProcess.sh

#	Oct 18, 2011: - BUG: %{min,max}_ens used ensemble indices, rather than numbers

#				  - disabled false-positives editing (removes too much good data on 2011_IWISE)

# CTD REQUIREMENTS

#	- elapsed		elapsed seconds; see note below

#	- depth

#	- ss			sound speed

#	- w				ddepth/dt

#	- temp			OPTIONAL; used for backscatter calculation (i.e. not very important)

#	- %lat/%lon		OPTIONAL

# 2-BEAM SOLUTIONS

#	- for beam-coordinate data, two separate two-beam solutions (w12 & w34) are calculated

#	- discrepancies can be indicative of package wake effects (e.g. MIXET data)

#	- for earth-coordinate data, w12 and w34 are simply copies of w

# 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 -m 1 catches those errors

#	  quite nicely

#	- even when the errors are not filtered with -m 1, they do not

#	  affect the w profiles, as long as the median bin values are used
