Altitude Factors and Change of Altitude in a Given Time from Meridian Transit

Altitude Factors: This form calculates the change in the altitude of a celestial body in one miute of time from meridian transit. The values are accurate if the altitude is between 6° and 86°, the lattitude is not more than 60°, and the declination is not more than 63°. The result is used as input to the following form.
