multiple instances of function/variable `ps` for different purposes

"ps" is used for different things in the code base.

• instance 1, related to peak center
  ps = based on original peak stats ; used in collection environment. may be useful in analysis.
• instance 2, related to aged g2 from two-time
  ps =
• instance 3a, get_timepixel_data comment on line 36
  ps =
• instance 3b, get_pvlist_from_post internal variable that is returned
  ps =
• instance 4, speckle modules with variable
  ps = Poission distribution. Docstring is good. no clarification needed

Instance 1

https://github.com/NSLS-II/pyCHX/blob/6e991bb1eb06d8fe1bc8f684ebfcec581ee57aba/pyCHX/chx_generic_functions.py#L996-L1006

There are notes in code to @mrakitin .
Is this used in analysis to not have to fit to find the center of a peak?
It seems it was associated with a Bluesky profile file. Is this new one used in bluesky?
What does "ps" mean in this context? peak stats? peak scaling?

Instance 2

show_g12q_aged_g2()
https://github.com/NSLS-II/pyCHX/blob/6e991bb1eb06d8fe1bc8f684ebfcec581ee57aba/pyCHX/Two_Time_Correlation_Function.py#L599-L621

Instance(s) 3

in xpcs_timepixelmodule in 2 functions
https://github.com/NSLS-II/pyCHX/blob/6e991bb1eb06d8fe1bc8f684ebfcec581ee57aba/pyCHX/xpcs_timepixel.py#L25-L36
"ps" is photon statitisics?
https://github.com/NSLS-II/pyCHX/blob/6e991bb1eb06d8fe1bc8f684ebfcec581ee57aba/pyCHX/xpcs_timepixel.py#L50-L72
"ps" is photon positions

Instance 4

in speckle* modules for fit_xsvs1. "ps" is Poisson distribution
