Tof

Tof#

class Tof(becExp)#

Bases: BecAnalysis

Tof time-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.
