SUNAZ - true north calculations program

SUNAZ is a set of computer programs comprising SUNAZ and SUNIN to calculate azimuth-by-hour-angle observations of the Sun to determine true north azimuth to an azimuth mark based on the observing proforma described in K.A. Weinert (1980), Notes on Geomagnetic Observatory and Survey Practice, Earth Science 5, UNESCO, paragraph 246, page 36, using the algorithm described in G.G.Bennett (1980), "A Solar Ephemeris for use with Programmable Calculators", The Australian Surveyor, Vol.30, No.3, pp 147-151.
