aAs discussed in the text, fitting errors range up to about 15 per cent (see also Paper I), but measurements made at different epochs can differ more than this, reflecting a larger intrinsic scatter.
bThe spectrum used by VP06 and P13 does not include the λ1400 feature, so we have used the measurement from Paper I for all samples.

aAs discussed in the text, fitting errors range up to about 15 per cent (see also Paper I), but measurements made at different epochs can differ more than this, reflecting a larger intrinsic scatter.
bThe spectrum used by VP06 and P13 does not include the λ1400 feature, so we have used the measurement from Paper I for all samples.
