interception_probability needs more testing about ascotracer HOT 3 CLOSED

@PaulMelloy I was going to raise this in a new issue but then I saw this issue. I am writing the spore deposition probability section, I tried to find 'deposition_probablity' , I couldn't find it in both mathematica and R scripts. However, the interception_prabability function seems to fit the description of deposition_probability function. I suspect interception_probability represents deposition_probability.

Please see the description below and let me know what do you think

This is the description of deposition probability in Art paper

In the model, the spore deposition probability (Sc) is used to convert potentially infective spores to number of successful infections. The deposition probability is calculated using an exponential function simcommonly used for estimating the fraction of the incoming radiation intercepted by a crop canopy
Sc = 1 – exp(–KSc × Phnt × V) (4)
KSc is the limit of the probability of deposition of potentially infective spores on susceptible growing points in a square meter area as the density of susceptible growing points (Phnt × V) approaches

This is interception_probability function in R script (and mathematica script).

#' Probability of Interception of Conidia

#' 'interception_probability()' estimates the probability of conidia not landing
#' on suceptible growing points
#'
#' @param target_density is the density of suceptible growing points
#' @param k is a dimensionless parameter
#' @example
#' interception_probability(3000,5)
#'
#' @Keywords internal
#' @nord

interception_probability <- function(target_density, k) {
1 - exp(-k * target_density)
}

from ascotracer.

I've come up with something like this for the manuscript

interception_probability <- function(target_density, k) {

  | 1 - exp(-k * target_density)
  | }

from ascotracer.

I am closing this issue. We always get 1, this means no conidia should be landing on host. We're getting disease so clearly conidia are landing on host. TBH interception probability is not relevant for within paddock dispersal because we're just dealing with paddocks, there is only chickpea crop, so conidia should not be intercepted by anything and land on chickpea. I have removed the conidial interception part from the ms

from ascotracer.
