I asked the very same question a long time ago, and the response was:
Analyze>Tools>Save XY Coordinates...
And it saves the 'X, Y, Value' in columns, see attached. This is perfect
format for putting into spreadsheet programs for analysis. A ResultsTable
would allow for copy/paste.

X,Y,Value
127,52,-1.257
128,52,0.923
129,52,-0.941
130,52,-0.941
131,52,-0.202
132,52,0.374
133,52,0.178
134,52,0.288
135,52,-0.334
136,52,0.713
