Collection of data from various sources needed for cosmic dose rate calculation
values.cosmic.Softcomp : | data frame containing cosmic dose rates for shallow depths (< 167 g cm^-2) obtained using the "AGE" program by Rainer Gruen (cf. Gruen 2009). These data essentially reproduce the graph shown in Fig. 1 of Prescott & Hutton (1988). |
values.factor.Altitude : | data frame containing altitude factors for adjusting geomagnetic field-change factors. Values were read from Fig. 1 in Prescott & Hutton (1994). |
values.par.FJH : | data frame containing values for parameters F, J and H (read from Fig. 2 in Prescott & Hutton 1994) used in the expression |
$$Dc = D0*(F+J*exp((altitude/1000)/H))$$
