TABLE /MATH

TABLE /MATH Expression1 [... ExpressionN]
Instead of storing the spectrum (channels) for each entry in the current
index, you can use any Sic mathematical formula (e.g. involving some R
buffer variables).
The following functions are also predefined (see e.g. HELP FUNCTION SDTV
for details):
STDV(dummy) integrated area (K.Km/s)
TPEAK(dummy) peak temperature (K)
VPEAK(dummy) velocity at peak (Km/s)
TDV(v1,v2) integrated area (K.Km/s) between velocities V1 and V2
TPEAKV(v1,v2) peak temperature (K) between velocities V1 and V2
VPEAKV(v1,v2) velocity at peak (Km/s) between velocities V1 and V2
For example, to create a table containing the integrated area of each
spectra, you can use:
TABLE Filename /MATH STDV(0)
To create a table of the RMS of each spectrum measured during BASElin-
ing, use:
TABLE Filename /MATH R%HEAD%BAS%SIGFI
And to create a table of the area, position, and width of the line fit-
ted with the command MINIMIZE for all the spectra, use:
TABLE Filename /MATH R%HEAD%GAU%RESULT[1] R%HEAD%GAU%RESULT[2] -
R%HEAD%GAU%RESULT[3]
Once used in XY_MAP, these tables will result in maps of integrated
area, RMS, line width, etc.
