3.3.4) The PIA SPD Window

The PIA SPD Window serves to control the processing from the SPD to the AAP level.  This is actually only necessary for SPD data produced by the OLP. Within the normal PIA processing, the conversion from [V/s] on the SCP level is directly done to fluxes and brightnesses ([Jy] & [MJy/sr]) on the AAP level.
It is reached via the button "Plot and Reduce Data" in the menu of the PIA Measurement Buffer Control Panel or it is automatically displayed when processing data from the PIA SCP Data Display Window. The maximum number of opened SPD Windows is restricted to two.

This chapter describes the PIA SPD Data Display window and directly associated sub-windows.

Basically, the SPD window (Figure 1) is divided into three rows:

Remark on Upper and Middle Row:

Since the upper row and the middle row are very similar to those of the ERD Window, the user is referred to the ERD description with the following differences for the middle row:

Array

This menu bar calls a submenu with additional features for array data. It offers the following options:

Process

This menu bar calls a submenu in order to process the whole measurement to the next level. The submenu offers the following possibilities:

Pixels Choice

This menu bar is active only for C100, C200 and PHT-S data, where several pixels are to be analyzed. It calls a submenu with the following options:
  • Individual Choice: This calls the PIA Display Choice window. For each display window the user can specify the pixel number whose signal will be plotted. After the selection the window will be refreshed with the plots for the new pixels chosen.
  • Serial Increment: This selects the next subsequent pixel to each of those shown. When pressing this button, in each window containing pixel N the signal corresponding to pixel N+1 will be plotted.
  • N Plots

    This button allows the number N of plot windows shown in the middle row of the SCP window to be selected. After a selection the window will immediately be refreshed, containing N plots. Please note that this number will be used also for further main level windows.

    HK

    This button calls a submenu for accessing the Housekeeping Menu to display the Housekeeping data associated to this measurement, as contained in the corresponding GEHK FITS product.

    The PIA Chopper Plateau Selection Window

    It is the same as described for the SCP Window: see the PIA Chopper Plateau Selection Window in section 3.3.3.
