In astrochron: A Computational Tool for Astrochronology

generate an insolation map using Laskar et al. (2004) insolation calculations

Description

Generate insolation maps using Laskar et al. (2004) insolation calculations. This is a wrapper function to calculate insolation using the palinsol package, following astrochron syntax.

Usage

insoMap(t=0,pick=0,S0=1365,output=F,verbose=T) 

Arguments

t	Time for evaluation, in kyr (negative for future, positive for past; valid from -21000 to 51000)
pick	Interactively pick (1) latitude to examine seasonal insolation at that latitude, or (2) day to examine insolation across latitude
S0	Solar constant, W/m^2
output	Output insolation matrix (if pick=0) or selected insolation transect (if pick = 1 or 2)? (T or F)
verbose	Verbose output? (T or F)

Details

This wrapper function generates maps with insolation calculations based on the Laskar et al. (2004) astronomical parameters, using the 'palinsol' package (Crucifix, 2016).

Option 'pick' will allow you to extract insolation by (1) latitude or (2) season.
