Information for mucalib.m calibrating muon parameters fstar and sigma0 for the expage calculator.
The code is assembled and fixed by Jakob Heyman (jakob.heyman@gu.se) 2016-2018 based on CRONUScalc
code (Marrero et al. 2016) from https://bitbucket.org/cronusearth/cronus-calc.

This code calibrates fstar and sigma0 for 10Be and 26Al production by muons using the CRONUScalc
calibration method with the Levenberg-Marquardt algorithm to fit the seven parameters below to
measured 10Be and 26Al depth profile data. The code is setup for calibration of data from four
sites:
Beacon Heights (Borchers et al. 2016; Marrero et al. 2016; Phillips et al. 2016; Balco 2017)
Leymon High (Braucher et al. 2013; Balco 2017)
Leymon Low (Braucher et al. 2013; Balco 2017)
La Ciotat (Braucher et al. 2011; Balco 2017)

Parameters:
* erosion rate ([g/cm2]/ka)
* attenuation length for 10-Be (g/cm2)
* attenuation length for 26-Al (g/cm2)
* fstar10 (scaled by 1.0e-3)
* sigma010 (scaled by 1.0e-30)
* fstar26 (scaled by 1.0e-3)
* sigma026 (scaled by 1.0e-30)

TO USE THE CODE:
1. Choose site in mucalib.m, line 14
2. Run mucalib.m
