ATOMIS is a web application that aims to search for observations in the ALMA archive for a given list of
sources and species.
The users can specify different filters on observations (angular and spectral resolutions, sensitivity, ...)
and on species (minimum and maximum Eup, Aij, maximum frequency uncertainty).
The user can either choose species on the CASSIS spectroscopic database (JPL[1], CDMS[2], LSD[3], NIST[4] and VASTEL[5]) or
upload spectroscopic files. It also allows the users to download the corresponding ALMA data products
such as fits files and to visualize them with ALADIN[6] and CASSIS[5,7].
In order to search for ALMA observations, ATOMIS uses the Astropy package[8] and some features of the
Alminer tool[9] (ALMA Archive Mining & Visualization Toolkit).
This project has received funding from the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme (grant agreement 949278, Chemtrip).
