12.2 Output Panel

Fig. 12.2 : Mspec0, pannello di visualizzazione

In normal observing conditions the four buttons (top left) must be as shown in fig. 11.2 (On-source GREEN and the other three GREY). The first button can appear as follows :

YELLOW : Slewing

RED : Calibration

BLUE : Off-Source

The axis scale and the unit of measure can be changed using the buttons under the graph. The spectra can be viewed individually (Plotting method : single), overlapped (Plotting method : overlap), in time succession (Plotting method : history).

Other buttons :

- PRINT : generates an encapsulated postscript file

- CLEAR : cancels the display

- SUSPEND : stops the visualization only

- GO-AHEAD : in Manual mode starts the data acquisition

 

The grey panel shows a cycle summary.

 

The output panel contains two sub-section also :

- Offset : a filter is applied, corresponding to the medium level of the 1080% total power level.

- Mov. avg : the medium level corresponding to the desired spectral points number (selected in the "bin" box) is subtracted.

- None
