#' Calculates Tmin for the Thomas TRC
#' 
#' Calculates the Tmin for the thermal response curve by subtracting w/2 onto
#' Topt.
#' 
#' %% ~~ If necessary, more details than the description above ~~
#' 
#' @param Topt The parameter Tmax
#' @param w The parameter w
#' @return returns the Tmin for the Thomas TRC. The lowest temperature at which
#' the rate is no longer positive.
