nating below the Pole, we can use those whose Declination isbetween 38£° and 90° and includes 24 in the list. Polaris itself could beutilised for this purpose, but its apparent orbit is so small that a starculminating Southwards and fairly near the celestial equator would bepreferable, provided… … Fig 2.LET X = LATITUDE ; S = DECLINATION.
