The originals of the Haleakala figures 3, 4 and 8 (photometer data) were images of data plotted on millimeter scale graph paper, with labels and explanatory text displayed in a somewhat haphazard manner. The scanned images we started with were full-page, and overflowed the screen to such an extent that they were unreadable. When reduced in size to limit the extent of screen overflow, the millimeter scale became a grey haze that obscured the plotted data. We have therefore modified these images in the interest of readability by:

We have made every effort to avoid altering the data points as originally plotted.
