lisa.pelt.pelt_settling_time(margin=1, init=0, final=1024, window=0.001048576, half_life=32, scale=1024)

Compute an approximation of the PELT settling time.

Parameters:

• margin – How close to the final value we want to get, in PELT units.

• init (float) – Initial PELT value.

• final (float) – Final PELT value.

• window (float) – PELT window in seconds.

• half_life (int) – PELT half life, in number of windows.

• scale (float) – PELT scale.

Note

The PELT signal is approximated as a first order filter. This does not take into account the averaging inside a window, but the window is small enough in practice for that effect to be negligible.
