Popis:	The Orbit Response Matrix (ORM) analysis is a method which allows to find the sources of discrepancies between design and real optics of an accelerator machine. In particular, with this technique one retrieves information about gradient errors, dipole corrector gain errors etc. Orbit response matrix is computed by measuring orbit deviations caused by single kicks of corrector magnets. With fitting the matrix one obtains the ion optics which best describes the real accelerator. The ORM analysis, presented in the paper, is employed to find error sources in the FAIR storage rings CR and HESR during and after the beam commissioning. The algorithm itself was implemented in Python programming language with a help of linear algebra libraries. The ORM analysis accuracy as well as its limitations are addressed in the paper.
