N2 - The paper 'Choirs, HI galaxy groups: catalogue and detection of star-forming dwarf group members' was published in MNRAS 433(1), 543 559 (Sweet et al. 2013). Two methods for calculating the H I deficiency parameter were presented in Section 3.7. For method (1) there was an error in the transformation used to scale our Survey for Ionization in Neutral Gas Galaxies (Meurer et al. 2006) R-band (AB) magnitudes (MagRAB) to the SuperCosmos magnitudes (MagRSC) on which Denes, Kilborn &Koribalski (2014) was based. The transformation should be MagRSC = -8.52 + 0.63MagRAB. We note that Denes et al. ( 2014) subsequently presented an updated, slightly different R-band scaling relation, which does not affect our results. In Fig. 1 we show the replacement H I deficiency figure. Methods (1) (upper panel) and (2) (lower panel, scaling from H a luminosity and R-band surface brightness) are now in closer agreement. Our main previous finding is unchanged: the Choir groups are not significantly HI-deficient in either method for calculating HI deficiency. HIPASS J1059-09 is now HI deficient in both methods, though not at a significant level. As before, HIPASS J1403-06 was found to be marginally HI deficient by method (2) and not method (1), and is likely dominated by high H a equivalent width starbursting galaxies. We thank Robert Dzud zar for discovering the error.
