    "abstract": "We explore the features of Flatte-like parametrizations. In particular, we\ndemonstrate that the large variation in the absolute values of the coupling\nconstants to the pi-eta (or pi-pi) and KKbar channels for the a_0(980) and\nf_0(980) mesons that one can find in the literature can be explained by a\nspecific scaling behaviour of the Flatte amplitude for energies near the KKbar\nthreshold. We argue that the ratio of the coupling constants can be much better\ndetermined from a fit to experimental data.",
