\begin{table}%T2
\caption{Relative (dimensionless) O~IV transition probability values. $A^{\rm rel}_{\exp}$
represent our experimental values (with estimated accuracies) related to the reference $A$ value
of the O~IV 340.355~nm transition. $A_{\rm N}^{\rm rel}$ are transition probabilities tabulated
by  NIST (\cite{NIST03}).$A^{\rm rel}_{\rm TK}$  denote experimentally  obtained data by the RLIR method
(Truhan \& Kiseljevskij \cite{Truhan67}).
Data in brackets denote absolute $A$ values related to the reference 340.355~nm
 O~IV transition (in $10^8$ s$^{-1}$).
Atomic data are taken from NIST (\cite{NIST03}).}\label{tab2}
