Column selection

This constitutes the central area of the xmmselect GUI. It consists of a vertically arranged list of pushable buttons, each corresponding to one numeric, string, or boolean column found in the specified input table. Each button is labeled with the name of the column it represents. To its left are up to two associated check buttons which, when being selected, mark the column as primary axis in the extraction of a an image or spectrum/histogram/rates curve, respectively (for more information on the function of the check buttons see below.

To the right of the button with the name of the column is a short framed label which specifies the types of the column:

label column type canonical value range
I8 8-bit integer $[-128, 127]$
U16 16-bit unsigned integer $[0, 65535]$
I16 16-bit signed integer $[-32768, 32767]$
U32 32-bit unsigned integer $[0, 4294967295]$
I32 32-bit signed integer $[-2147483648, 2147483647]$
R32 32-bit real $[\approx-10^{38}, \approx+10^{34}]$
R64 32-bit real $[\approx-10^{308}, \approx+10^{308}]$
S string n/a
B boolean true/false
To the right of this label are more GUI elements whose type depend on the type of the column.

If the number of data columns in the input is large the list of push buttons might become too large to fit on the screen. In this case the entire middle area will become vertically scrollable as shown in this figure.
