c19a514027Added back the captured atom counting and the jackknife error estimation method as developed by Jianshun Gao, retained the bootstrap method and the counting that goes with it now corrected to prevent counting the same atoms repeatedly and also to reduce the atom count if they are lost. There is now an agreement between the two methods as to what the loading rate is with the bootstrap method giving a slightly lower estimate.Karthik Chandrashekara2021-07-16 15:57:16 +0200

4051549b27Increase of 5% was meant for cut-off velocity and not the capture velocity, correction was made accordingly.Karthik Chandrashekara2021-07-16 15:50:08 +0200

6cde617bb4Fixed the Saturation parameter calculation was not indexing over the local saturation intensity array.Karthik Chandrashekara2021-07-14 20:05:40 +0200
411375b464Average velocity of the distribution of atoms inside the oven here cancels with the normalization of the distribution of atoms coming out of the oven so it can be removed as long as that normalization is also removed!Karthik Chandrashekara2021-07-14 20:04:34 +0200
f789a7ad6aModified to determine the distance between atom and the z-axis and checked to see if that is within the diameter of the beams - this makes sense since the beams are crossed and the condition that the distance be smaller than the beam diameter holds only along the y-axis.Karthik Chandrashekara2021-07-11 14:51:17 +0200
5b91c20246Major changes - rewrote how autocorrelation, resampling and determination of loading rate is done.Karthik Chandrashekara2021-07-11 14:47:13 +0200

b4e28e09dbWrapped the calculation of the "reduced" Clausing factor - which is the probability of an atom exiting from the oven within a smaller solid angle as determined by the apertures/orifices along the way.Karthik Chandrashekara2021-07-11 14:40:43 +0200
bb5f70ce7fWrapped the calculation of the collision event probability in its own function.Karthik Chandrashekara2021-07-11 14:39:26 +0200

b6d56e9e7bWrapped the exit condition in to its own function now checking if the position, velocity meet certain criteria and account for collision events.Karthik Chandrashekara2021-07-11 14:35:54 +0200
