+==== Challenge ====
+ To test which tools are useful to obtain information about spiral arms properties, in samples where extinction and Gaia errors have been implemented.
+ Following the work that L. Chemin started in the last year in Surrey, we can try to study the feasibility of using the TW method to find pattern speed of spirals. We can evaluate the method first in a pure simulation (without errors and extinction) and then in more realistic data that include Gaia errors and extinction.
+ It would be interesting to test when other tools like Fourier based ones are also useful.
+==== mock data (will be uploaded soon): ====
+ Test particle simulations with single spirals and also with spirals + bar.
+ Tools to add realistic extinction and Gaia errors.
