21 Jan 2014: 2012), meaningthat we can test for differences between the BASS spectrum and theolder IRAC data (2006) at 3.5 to 4.5µm (also shown in Figure 2).The BASS/IRAC flux ... 4.2 A transition disc? To test whether HD 166191 can be modelled as a protoplane-tary

17 Dec 2014: We also propose that a useful hypoth-esis to test is that the planet and planetesimal systemsseen on the main sequence are already in place dur-ing the protoplanetary disk phase, ... Hence a useful hypothesis to test is that the plan-. etary system and

23 Jan 2014: While Figs 2b and 2d provide the best estimate of theunderlying inferred accretion rate distributions in the sub-samples, we will also use Fisher’s exact test to assign a

7 Jan 2014: Bryden). As a test of such theories, many attempts have been madeto identify statistical correlations between debris and planetproperties.

18 Oct 2014: A Fisher’s exact test shows that there is only. a 0.7% chance of detecting rates as discrepant if the two groups had the same distribution.
