+**GSoC Application Tag:** testing
 **Description:** Testing a scientific code like TARDIS is very important. We need to ensure that the scientific insights we gain using the code are not based on bugs. Open collaboration with GitHub is great, but the more people work on the code the more opportunities there are to introduce bugs. Making sure that the code doesn't change or only changes as we expect it, is thus an important part of TARDIS development.

 **Description:** TARDIS studies how light travels through a supernova and how it ultimately appears to us. We are researching this process and thus are interested in analyzing TARDIS outputs in great deal. This means that we aim at capturing the full state of a TARDIS calculation in more detail. TEP002 describes the ideas in some detail and we want you to help us to implement these.

+**GSoC Application Tag:** atomic dataset
 **Description:** In addition to the input parameters (brightness of the supernova, ejected mass of the different chemical elements, etc.), TARDIS requires data for describing the structure of atoms from different elements (e.g. a sodium atom is differently structured than an iron atom; see the figure for a quick overview for carbon).

+**GSoC Application Tag:** spectral synthesis
 **Description:** TARDIS's main task is to create spectra that can be compared with observations. In order to use TARDIS to estimate parameters of real supernovae, we need to select TARDIS simulation parameters in such a way so as to produce spectra resembling those of real supernovae. When having a real spectrum, however, we don't know what those simulation parameters may be.

 This project requires a bit of physics knowledge.
-**Your first objective if you choose to accept the mission:** Implement a simple counting estimator, storing the number of Monte Carlo packets that come into resonance with each atomic line transition. For this, look into the main Monte Carlo part of TARDIS and find the location where the ''j_blue_estimators'' are incremented. This would be the place to insert your counters.

+"Bonus objective:" Once the counter is properly working, you could try to implement an estimator for the line absorption rates (see Equation 11 in [[http://adsabs.harvard.edu/cgi-bin/nph-data_query?bibcode=1999A%26A...345..211L&link_type=ARTICLE&db_key=AST&high=|Lucy 1999]]). In an additional step, these level absorption rates could be used to calculate level absorption rates (see Equation 19 in [[http://adsabs.harvard.edu/cgi-bin/nph-data_query?bibcode=1999A%26A...345..211L&link_type=ARTICLE&db_key=AST&high=|Lucy 1999]]).
+**Hints:** As mentioned above, understanding what incrementing ''j_blue_estimators'' means, is the key to the first objective. Physically, it measures the energy of all photons which can come into resonance with a particular line. Photons/packets not necessarily have to interact with the line to be counted. The relativistic Doppler shift just has to shift their frequency far enough so that it matches the frequency of the line. Taking all this into account, you will realise that the ''j_blue_estimators'' behave very similar to the counter you are supposed to implement.

+**GSoC Application Tag:** config system
 **Description:** TARDIS is a complex piece of software and has many options that can be switched on and off. This means that the Configuration modules have to be able to take a variety of input forms, parse them, validate that the input is in someway sensible (that if a float is expected there is no string given). We have thought about how to make this easier to use and have come up with YAML tags. They are a great way to parse strings to the right format and make sure that the input is valid.

+**GSoC Application Tag:** atomic/model/plasma integration
 **Description:** TARDIS needs to calculate the Plasma state very often during the runtime. TARDIS should also be able to use different modules with different approximations how to calculate the plasma state. Last year we updated the plasma module to allow a more modular approach. While we got far, this new framework is not yet completely embedded in the code and we will need your help with finalizing the integration.
