The injection-recovery MATRIX (Multi-phAse Transits Recovery from Injected eXoplanets) Toolkit creates grids of scenarios with a set of periods, radii, and epochs of synthetic transiting exoplanet signals in a provided light curve. Typical injection-recovery executions consist of 2-dimensional scenarios, where only one epoch (random or hardcoded) was used for each period and radius, which may reduce accuracy. MATRIX performs multi-phase analyses needing only a few parameters in a configuration file and running one line of code.

WATSON (Visual Vetting and Analysis of Transits from Space ObservatioNs) enables a comfortable visual vetting of transiting signal candidates from Kepler, K2, and TESS missions. The code looks for transit-like signals that could be generated by other sources or instrument artifacts and runs simplified tests on scenarios including transit shape model fit, odd-even transits checks, and centroids shifts. It also considers optical ghost effects, transit source offsets, and several other scenarios. WATSON then computes metrics and flags problematic signals.
