¹ Calculated according to Stone (2000).
² 2.2% of surface production assigned to muons (Stone, 2000)
³ 2.6% of surface production assigned to muons (Stone, 2000)
⁵ Calculated using the paleomagnetic intensity records of Guyodo and Valet (1996), McElhinny and Senanayake(1982), the paleo-pole positions of Ohno and Hamano (1992), the paleomagnetic correction procedure of Nishiizumi et al. (1989), and latitude/altitude scaling factors from Stone (2000).

⁴ Assuming rock density of 2.7 g/cm³
⁵ Topographic shielding was less than 10^-3 for all samples.
