Notes.Upper limits are given at the 3σ confidence level and determined assuming a broadening parameter of b = 2 km s−1. In the cases of 120327A, 120909A, 121024A and 141109A, the observed velocity width is close to the instrumental resolution, and therefore we measured the column density for b = 2 km s−1 and b = 10 km s−1 in order to determine a realistic range for the total H2 content.
