Table 1 Analysis of covariance model that was applied to the data for an interrogated spot. This table gives the typical degrees of freedom and the approximate expected mean squared errors for the sources of variation estimated under the experimental design. The reported F-ratios are the median of the 32,112 analyses. This median is the vertical red line in the box of Figure 1. The p-value is for the tabled F-ratio with numerator degrees of freedom as tabled and 34 denominator degrees of freedom.
