(Reproduced from [22]) (a) The state of CMB anisotropy detections in 1993. The points are from COBE [15], Python [17], MAX [18] and IAB [19]. Also shown is the upper limit from the OVRO NCP experiment [21]. (b) The state of the field in early 1998. Shown are COBE [36], FIRS [37], Tenerife [38], SP94 [39], Python [40], ARGO [41], MAX [42], Saskatoon [24], CAT [25], and the OVRO RING5M [23]. (The solid line is a CDM model with , and , and is also indicative of the state of late 20th century cosmology).
