| - | One important piece of TARDIS is the calculation of the plasma state. That means that it is also crucial to ensure that the results from these calculations do not change unexpectedly. But we sometimes introduce changes that do affect the result in an expected way. This requires us to change the values that the test checks against in a controlled way. This project aims at making it easy for us to generate "reference" data and update this reference data. | + | One important piece of TARDIS is the calculation of the plasma state. That means that it is also crucial to ensure that the results from these calculations do not change unexpectedly. For this purpose we use unit tests of isolated parts of the plasma state calculations and compare the results to pre-computed reference data. Naturally, whenever we improve, expand or alter the implemented physics underlying the calculation, we have to also modify the reference data. This project aims at making it easy for us to generate and update reference and to automate this process. |

| For this project you would help us make parsers for a variety of formats from a collection of atomic data sources (see the TEP) and in the second part put this into a database. The assembled database will not only be very interesting for us, but also for many other fields of astronomy that do rely on atomic data. A useful resource of understanding atomic structure description can be found in http://www.physics.byu.edu/faculty/bergeson/physics571/notes/L27spectnotation.pdf. | For this project you would help us make parsers for a variety of formats from a collection of atomic data sources (see the TEP) and in the second part put this into a database.

| - | **Your first objective if you choose to accept the mission:** Write a download function to download the atomic weights and symbols and so on from this page http://physics.nist.gov/cgi-bin/Compositions/stand_alone.pl?ele=&all=all&ascii=html. Then build a simple sqlalchemy database with one table and put it in there. "Bonus objective": Write a parser for (http://kurucz.harvard.edu/atoms/1401/gf1401.gam) using pyparsing. | + | In GSoC 2016 we created a package that compiles all of this information into a database named Carsus (see http://carsus.readthedocs.io/en/latest/). For this year we aim to strengthen the link between Carsus and TARDIS and also include more atomic data into Carsus. |

| + | **Your first objective if you choose to accept the mission:** Use the script (https://github.com/tardis-sn/carsus-db/blob/master/scripts/create_hdfstore.py) to generate an HDF store - then implement a meta table in the HDF file that stores the units of the columns. | ||
