# 2D SFCS AC
# 2D one component correlation function for for perpendiculat SFCS.
# Model function for PyCorrFit.

# The detection profile is eliptical, as the focus passes the membrane
# perpendicular to its axis of symmetry.
# The axis ratio / strucure parameter is defined as:
# SP = semi-major-axis / semi-minor-axis (wz/w0)

## Parameters
# Number of particles
Nob = 40.0
# Diffusion time
taudiff [ms] = 1.0
# Axis ratio / structural parameter
SP = 5

gFirst = 1/sqrt(1+tau/taudiff)
gSecond = 1/sqrt(1+tau/(taudiff*SP**2))

# Correlation function
G = 1/Nob * gFirst * gSecond
