${{\mathit D}_{{{s1}}}{(2536)}^{\pm}}$ $I(J^P)$ = $0(1^{+})$ J, P need confirmation.

Seen in ${{\mathit D}^{*}{(2010)}^{+}}{{\mathit K}^{0}}$, ${{\mathit D}^{*}{(2007)}^{0}}{{\mathit K}^{+}}$, and ${{\mathit D}_{{{s}}}^{+}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$. Not seen in ${{\mathit D}^{+}}{{\mathit K}^{0}}$ or ${{\mathit D}^{0}}{{\mathit K}^{+}}$. $\mathit J{}^{P} = 1{}^{+}$ assignment strongly favored.
