Since we submitted this article the field of CMB anistropies has refused to stay still, and there have been several significant developments. Firstly, the situation with regard to the COBE value of n has been clarified. The best fit to the two-year data is 1.10 ± 0.32 including the quadrupole, and 0.87 ± 0.36 excluding the quadrupole (Górski 1994). Similarly the value of Qrms - PS is 20 µK, rather than the earlier 17 µK. Secondly, the new MAX data (Devlin et al 1994, Clapp et al 1994) show consistently high detections at the half-degree scale in all three regions scanned. This has added support to the reality of the Doppler peaks. Lastly, there is a further claimed high detection on degree scales from an experiment based at the Italian Antarctic Base of Which we have recently become aware (Piccirillo & Calisse 1993). There are also a couple of places where assumptions we made about experiments have turned out to have been wrong: the Python point in Figures 3 and 4 is too low by a factor of approximately 3; and the window function for ARGO in Figure 5 is too high by a factor of 4 (P. de Bernardis, private communication).
