Tof#
- class Tof(becExp)#
Bases:
BecAnalysisToftime-of-flight expansion analysis for thermal clouds.For scans with
BecExp.ScannedVariable=="TOF", fits \(R^2\) vs \(t_{\mathrm{TOF}}^2\) along x/y to extract temperature \(T\), in-situ radii, trap frequencies, and phase-space density. Displays fit lines and a parameter table.- Associated Charts:
