CFM Graphing Options
Allows the user to customize the CFM display in CIRAS-2. This function is also available within the main
CIRAS Graphing Preferences (Settings – Graph – Preferences).
CFM Time Plot
Average
Fluorescence
If selected, the average fluorescence is plotted as a green line. The
fluorescence signal is averaged every 1.6 seconds in order to
correspond with photosynthesis measurements. Note, average
fluorescence can also be plotted on the CIRAS display (one of four
possible parameters that can be selected.
Span
Fluorescence data can be displayed over 2,3 and 4 minute time
intervals. In all cases, the last 1 minute is discarded when the full
span has been reached.
Fl Max
Maximum fluorescence setting (0-4000 bits) plotted against Span
(minutes)
Fl Min
Minimum fluorescence setting (0-4000 bits) plotted against Span
(minutes)
CFM Data Plot
Pn v phiPSII
When selected, a Pn (assimilation) record is taken and plotted against
phiPSII.
Pn range: 0-100
phiPSII range: 0.1 - 0.85.
Pn v ETR
When selected, a Pn (assimilation) record is taken and plotted against
ETR.
Pn range: 0-100
ETR range: 10 – 1000
CFM Graphing options are stored on a per definition basis within the .cfm settings files.
