5.2 Options to process data
Go to the
Data
menu to select how data is processed.
•
Use
Reprocess Data
to apply a different calibration or other setting to saved data.
•
Use
Show Data From Sensor
to show a graph of saved data.
•
Use
Convert APF Data
to convert APF data from the from binary to full_ASCII so data
can be re-processed (2000 m sensor only.)
•
Use
Compare Calibration
to compare two calibrations from the same sensor.
The SUNA uses the files below to process data:
•
The .xml instrument package file. For Windows, this is C:\Users\%USERNAME\My
Documents\Sea-BirdScientific\SUNA. For Mac OS X, this is /Users/Home/Sea-
BirdScientific/SUNA.
•
The raw data file to process.
•
The calibration file for the sensor.
5.2.1 Convert SUNA raw data
The Convert SUNA raw data function has been replaced with "Transmit Data from
Sensor" in the software. Go to the
Data
menu and select
Export Data
to transmit the data
from the SUNA. Refer to
Export data to .csv or MS Excel format
on page 43 for details.
5.2.2 Show SUNA data
Use
Show Data form Sensor
to see the data that has been saved on the PC.
The SUNA uses the files below to process data:
•
The .xml instrument package file. For Windows, this is C:\Users\%USERNAME\My
Documents\Sea-Bird-Scientific\SUNA. For Mac OS X, this is /Users/Home/Sea-Bird-
Scientific/SUNA.
•
The raw data file to process.
•
The calibration file for the sensor.
1.
Push
Show Data from Sensor
.
2.
If necessary, push
Browse
to find the .xml "Instrument Package File" that is saved on
the PC. A typical file is "SUNA_
xxx
_001.xml, where
xxx
is the serial number of the
sensor.
3.
Push
Browse
to find the "SUNA Raw Data File" to see the data that is saved on the
PC.
4.
Push
Browse
to find the current "SUNA Calibration File" on the PC. A typical file is
SUNA_
xxxn
.CAL, where
xxx
is the serial number of the sensor, and
n
is the
calibration version.
5.
Push
Finish
.
The saved data shows in the
Time Series
tab.
5.2.3 Reprocess SUNA data
The user may find that it helps to use the
Reprocess Data
option under some conditions.
•
The settings for the sensor were incorrect. Use the "Reprocess" option to correct for
this, such as when a sensor was deployed in seawater, but set up for fresh water.
•
The data that is collected has changed over an extended deployment. Data is
processed with an updated reference spectrum file, and compared to the original
reference.
•
Water temperature and salinity data are collected. These can be put together with the
spectral data from the sensor to get more accurate nitrate data (Sakamoto et al.
2009).
