The stack is scaled so that the [LGM](https://en.wikipedia.org/wiki/Last_Glacial_Maximum)-to-present \nchange is assumed to be 1.0 ‰ in accordance with the pore-water estimate of \n[Schrag et al. 1996](https://doi.org/10.1126/science.272.5270.1930). The \npackage is adapted from the ice-volume correction in [Tierney et al. 2017](https://doi.org/10.1130/G39457.1).\n\n\n## Example\n\nStart by importing `erebusfall`, `numpy`:\n\n```python\nimport erebusfall as ef\nimport numpy as np\n```\n\n...and creating a hypothetical proxy time \nseries...\n\n```python\nage_ka = np.arange(0, 20, 1)\nproxy = np.random.normal(loc=-2.0, size=len(age_ka))\n```\n\nNow we can plug this into `ef.icevol_correction()` with a few key options:\n\n```python\nproxy_adjusted = ef.icevol_correction(age_ka, proxy, \n                                      proxytype='d18o', \n                                      timeunit='ka')\n```\n\nWe first plug in the proxy age and proxy values. The `proxytype='d18o'` \nindicates that we're dealing with δ18O. We can set `proxytype='dd'` for a δD \nrecord. The `timeunit` argument indicates that `age_ka` is in thousands of \nyears before present. There are also options for for \"years BP\" and \n\"million years BP\". The output from the function, `proxy_adjusted`, is the \ncorrected isotope proxy as a numpy array.\n\nSee `help(ef.icevol_correction)` for more documentation.\n\n## Installation\n\nYou can install the package [from PyPI](https://pypi.python.org/pypi/erebusfall) with\n\n```\npip install erebusfall\n```\n\nIf you want to use `conda`:\n\n```\nconda install erebusfall -c sbmalev\n```\n\n## Development and Support\n\nSource code is [hosted online](https://github.com/brews/erebusfall) under an Open \nSource license.
