  We have performed the most comprehensive resonance-model fit of
$\pi^-\pi^-\pi^+$ states using the results of our previously published
partial-wave analysis (PWA) of a large data set of diffractive-dissociation
events from the reaction $\pi^- + p \to \pi^-\pi^-\pi^+ + p_\text{recoil}$ with
a 190 GeV/$c$ pion beam. The PWA results, which were obtained in 100 bins of
three-pion mass, $0.5 < m_{3\pi} < 2.5$ GeV/$c^2$, and simultaneously in 11
bins of the reduced four-momentum transfer squared, $0.1 < t' < 1.0$
$($GeV$/c)^2$, are subjected to a resonance-model fit using Breit-Wigner
amplitudes to simultaneously describe a subset of 14 selected waves using 11
isovector light-meson states with $J^{PC} = 0^{-+}$, $1^{++}$, $2^{++}$,
$2^{-+}$, $4^{++}$, and spin-exotic $1^{-+}$ quantum numbers. The model
contains the well-known resonances $\pi(1800)$, $a_1(1260)$, $a_2(1320)$,
$\pi_2(1670)$, $\pi_2(1880)$, and $a_4(2040)$. In addition, it includes the
disputed $\pi_1(1600)$, the excited states $a_1(1640)$, $a_2(1700)$, and
$\pi_2(2005)$, as well as the resonancelike $a_1(1420)$. We measure the
resonance parameters mass and width of these objects by combining the
information from the PWA results obtained in the 11 $t'$ bins. We extract the
relative branching fractions of the $\rho(770) \pi$ and $f_2(1270) \pi$ decays
of $a_2(1320)$ and $a_4(2040)$, where the former one is measured for the first
time. In a novel approach, we extract the $t'$ dependence of the intensity of
the resonances and of their phases. The $t'$ dependence of the intensities of
most resonances differs distinctly from the $t'$ dependence of the nonresonant
components. For the first time, we determine the $t'$ dependence of the phases
of the production amplitudes and confirm that the production mechanism of the
Pomeron exchange is common to all resonances.
