\caption{\label{table:h2}Line fluxes measured along slit~\#1 ($\rm PA= 0\degr$) and slit~\#2 ($\rm PA=50\degr$) in units of $10^{-18}$~W~m$^{-2}$. We also give significant line flux ratios and results
such as the ortho-to-para ratios ($\phi_1$, $\phi_2$ and $\phi_3$), the extinction ($A_K$) and the excitation temperature ($T_{\rm ex}$).}

$^{(a)}$ This line falls in a region of poor atmospheric transmission; the indentification as 1$-$0 S(3) is therefore dubious and it is discarded from the analysis.
$^{(b)}$ This line ratio has not been corrected for extinction.
