The splitter for the Discharge Measurement Summary has been repositioned to display 6
measurements plus statistics by default.
The Summary only displays data for completed transects.
Export to .dis from discharge summary table includes Start Date.
12. Site Information
Site Information can be edited/changed in post-processing and all changes saved to the
workspace. Any modified values are displayed in green text – just like all other fields. Note:
In some cases fields that have not been changed are displayed in green. This is because
the original Site Information fields may have been initialized incorrectly.
13. Lock Measurements
Individual measurements can now be locked. This means that once a measurement is
locked by pressing the
Lock Measurement button on the Processing Toolbox toolbar any
changes to the settings will not be saved to the workspace. A measurement can be un-
locked by pressing the
Lock Measurement button a second time.
14. Processing Tools
Heading Correction
added to the Thresholds tool. This setting should be used for correc-
tions to the Heading for individual transects. The Magnetic Declination should be constant
for all transects at a site and the Apply to All button can be used for all transects without af-
fecting individual heading corrections.
Composite Tracks option added to the Thresholds tool. This setting by default is ON, in
both software and firmware. When disabled the track is calculated only using the selected
reference and not a combination of the best possible references.
15. System Test
System Test is logged to a text file.
16. MATLAB Export
Bottom-Track Velocity label is output as BT_Vel (previously Bt_Vel).
Units are removed from the names and are stored in a separate substructure within each of
the root structures.
17. Loading Data File
Data files are loaded in chronological order.
18.
Increased Precision on ALL Parameters
The precision has been increased (from float to double) on all values used in the software.
Float has a precision of about 6 digits and doubles have 15. This means that the previous
version may have done some rounding when dealing with large numbers of samples. The
most observable difference between 1.00 and 1.50 could potentially be in the third or more
significant digit of the discharge, but in most cases the variation would be extremely small.
