Data file layouts and data groups

If you want to get a good idea of how the data files will look, you can run the PC

SunData program in the emulator mode. The general presentation of the results on

screen will be similar to that in the eventual data file.

The one major exception to this is in the

All mode when the 64 individual

photodiode readings are listed. On the PC screen they are shown as 4 rows of 16

values, whereas in the

.CSV data files they occupy 64 adjacent columns (from handle

to tip of the probe) to the right of the notes field.

A single data file can contain a mixture of layouts. The column headings will be

different for different combinations of equipment (BFS or not) and measurement

(LAI or PAR or All) that you have chosen. Each time there is a change, the headings

and titles will be revised to start a new group and give you a complete "audit trail"

for your measurements. Each group contains readings with exactly the same settings.

When a new group is started, you can create a group title for it from

Menu,

Settings, Titles, Enter

. The group title is automatically cleared when a new group is

formed.

Group numbering

Data groups are numbered sequentially, starting from group 1 when the data file is

created. You can't edit the group number (in the way that you can edit Plot and

Sample numbers), but you can give it a title.

The group number is incremented automatically whenever you re-start the SunData

program after exiting, or when you change a critical setting, that is:

• any parameter in the

Settings menu

• any data or configuration file change.
