In this talk, I will briefly introduce Slovak instrument AMOS - all-sky meteor orbit system. We designed and developed a GUI tool for calculating and visualizing trajectories of meteors in Earth's atmosphere and Solar system from multiple-station observations. The current version of the program includes calculation of 1) atmospheric trajectory and velocity, 2) Solar system trajectory, 3) photometric mass, 4) dark flight and impact, 5) Monte Carlo simulation of errors. The program is written in Lazarus/Object Pascal and can be run under Windows as well as Linux systems. Numerical simulations and graphical outputs are produced in R.
In the second part of the talk, I will discuss the python-based photometry pipeline by Mommert (2017) for reducing 4-colour MuSCAT2 images. We implemented several modifications to significantly increase the number of successfully reduced images. I will discuss how the modifications combine data through colors as well as time to obtain more results.
