Here is Gary's example done by Pub 208 with all three reductions on one side of a standard index card. Very quick. Figuring the azimuth by slide rule completes the task. The graph plots so that any observation between 1800 UT and 1840 UT will conveniently give Hc for each minute of time. Constructed the whole thing in about 45 minutes.
