    • Although the data in the X and Y quadrants were taken on different samples, all photoemission groups consistently report a larger gap along the diagonal in the X quadrant than the Y quadrant.

    • Two of the data points in the X quadrant are close to the crossing of the main and superlattice bands, so it is unclear which band to assign them to. For the same reason, though, it makes little difference in the fits whether they are assigned to one or the other.

    • A gap which is the square of the d wave gap has the lowest rms error of any single function fit we have looked at, with an error only slightly larger than that of the |d|-c gap (the latter having two fit parameters). A gap of this type has been suggested by P. W. Anderson.

    • The data set is sparse enough in the Y quadrant that we cannot definitively rule out a d wave gap of the form cos(kx)- cos(ky). Such a gap, though, is hard to reconcile with data points in the X and Y quadrants near 35°, even allowing for substantial error bars.
