AMPEL-HU-astro

Contributed Ampel units from HU/DESY group
Installing

Install poetry. If you install poetry with conda, be sure to install it in its own environment, e.g. conda create -n poetry.
git clone https://github.com/AmpelProject/Ampel-HU-astro.git; cd Ampel-HU-astro
Check your virtualenv setup with poetry env info (or conda run -n poetry poetry env info if using conda). The output should include:
Virtualenv
Python: 3.10.x

If not, point poetry at an installation of Python 3.10 with (conda run -n poetry) poetry env use PATH_TO_PYTHON_310
(conda run -n poetry) poetry install -E "ztf sncosmo extcats notebook"
cd notebooks
(conda run -n poetry) poetry run jupyter notebook

This will allow a number of Demo / access / development notebooks to be run. Note that most of them
requires an access token if data is to be retrieved.
Provided units

T0 units (alert filters):

LensedTransientFilter
PredetectionFilter: Filter derived from the DecentFilter.
RandFilter
RcfFilter: Filter for the ZTF Redshift Completeness Factor program..
RedshiftCatalogFilter: Filter derived from DecentFilter designed to only accept transients located close to a galaxy in a catalog, and within redshift bounds.
SimpleDecentFilter: General-purpose filter devloped alongside DecentFilter but without use of external catalogs.
StellarFilter: a.k.a. as the IndecentFilter, i.e. an inversion of the DecentFilter mainly used for finding extragalactic objects.
TransientInClusterFilter: Filter derived from the DecentFilter, in addition selecting candidates with position compatible with that of nearby galaxy clusters..
XShooterFilter: Filter derived from the DecentFilter, in addition selecting very new transients which are visible from the South.
