Datasets for Testing DecomposeR

Description

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.
