Abstract
It is shown that the and the in our 12-GeV/c experiment fit poorly to the double-pole structure reported for the meson. The probability that our data agree with the double-pole hypothesis is less than 1% for the and completely negligible for the , although both resonances are fitted well by a Breit-Wigner shape. Our mass resolution is ±7 MeV at the and ±5 MeV at the .
