apd

Analysis Production Data

|LHCb software| |PyPI version| |Conda-forge version|

Programmatic interface to the LHCb experiment Analysis Productions database, which allows retrieving information about the samples produced. It queries a REST endpoint provided by the web application, and caches the data locally.

Usage

The apd Python package is available in the lb-conda default environment.

From Python

The Python module allows interacting from analysis scripts, doing e.g.

::

In [8]: import apd

In [9]: datasets = apd.get_analysis_data("SL", "RDs")

In [10]: datasets(datatype="2012", polarity="magdown") Out[10]: ['root://eoslhcb.cern.ch//eos/lhcb/grid/prod/lhcb/MC/2012/BSNTUPLE_MC.ROOT/00110970/0000/00110970_00000002_1.bsntuple_mc.root', 'root://eoslhcb.cern.ch//eos/lhcb/grid/prod/lhcb/MC/2012/BSNTUPLE_MC.ROOT/00110970/0000/00110970_00000005_1.bsntuple_mc.root', 'root://eoslhcb.cern.ch//eos/lhcb/grid/prod/lhcb/MC/2012/BSNTUPLE_MC.ROOT/00110970/0000/00110970_00000003_1.bsntuple_mc.root', 'root://eoslhcb.cern.ch//eos/lhcb/grid/prod/lhcb/MC/2012/BSNTUPLE_MC.ROOT/00110970/0000/00110970_00000001_1.bsntuple_mc.root', 'root://eoslhcb.cern.ch//eos/lhcb/grid/prod/lhcb/MC/2012/BSNTUPLE_MC.ROOT/00110970/0000/00110970_00000004_1.bsntuple_mc.root']

The apd-cache command allows caching the Analysis metadata to a specific location.

Design

Analysis Production information endpoint

This module allows downloading and using Analysis Productions information from the endpoint https://lbap.app.cern.ch/

Details about the endpoint can be found at https://lbap.app.cern.ch/docs#/stable.
