&DRIFT: DRIFT: TRACK


graph

The following graphs can be produced:

The graphs can be customised with the FUNCTION-GRAPH option which takes as argument a function of the following parameters:

Variable Meaning Unit
AVALANCHE Gain over the drift path numeric
LENGTH Drift line path length cm
DIFFUSION Integrated diffusion microsec
LOSS Survival probability numeric
TIME Total drift time microsec
X_END or R_END x Or r at drift line end cm
Y_END or PHI_END y Or phi ar drift line end cm or degrees
Z_END z At drift line end cm
X_START or R_START x Or r at drift line start cm
Y_START or PHI_START y Or phi ar drift line start cm or degrees
Z_START z At drift line start cm

Further details on the survival probability can be found under the method used to integrate the attachment coefficients.

Care should be taken that the AREA is chosen sufficiently large to let the particles reach their target.

You may switch off the printing and plotting of both drift lines and the plotting of isochrones if you're only interested in the graph.

The graph is drawn either as a line or as a set of markers, depending on the setting of the MARKER and SOLID options.

[By default, no graphs are produced. The set of requested graphs is remembered from one call to the next.]


MARKER

The options MARKER and SOLID determine the way the graphs are plotted.

MARKER means that all points are represented by small symbols, e.g. crosses. The symbol that is chosen, as well as its size and colour are taken from polymarker representation FUNCTION-1.

SOLID means that they are joined by straight line segments. The line type, width and colour are taken from polyline representation FUNCTION-1.

[The initial default is SOLID.]
