DecomposeR.Datasets | R Documentation |
Datasets for testing DecomposeR: the ace
dataset is from
from Sinnesael et al. (2016), the cip2
and cip3
data sets are
from the signals 2 and 3 of the CIP project (Sinnesael et al., 2019),
respectively, and cip1
was derived from cip1_raw
which is a rasterisation of the .tif image
provided as signal 1 of the CIP project. A real case study is also provided,
out of ODP 926 in Ceara Rise, limited between 5 & 9 Millions
of years ago (Ma): the data sets z13 and z13amp are from Zeeden et al., 2013,
and are respectively the greyscale, and its amplitude modulation for the
eccentricity; w17 is from Wilkens et al., 2017, which proposes
a revised splice for magnetic susceptibility; sc97amp is the
amplitude modulation of eccentricity as it was calculated on the magnetic
susceptibility by Shackleton & Crowhurst (1997). Excerpts from the Laskar
et al., 2004 solution are further provided from
http://vo.imcce.fr/insola/earth/online/earth/online/index.php: they are
the insolation input for the CIP1 signal (cip1_imput), and various solutions
for precession, eccentricity and obliquity for given time intervals (in
millions of years ago): La04_pre_0_20, La04_ecc_6_8, La04_obl_6_8 &
La04_pre_obl_5_9.
