Constellation:

Type initial epoch (epoch1), final epoch (epoch2) and needed coodinates (equatorial a₁, d₁ for epoch1, ecliptic l₁, b₁ for epoch1 or galactic l,b) and press corresponding "SUBMIT" (if EPOCH2=EPOCH1, EPOCH2=EPOCH1+10). Press "CLEAR" before the next calculation.

Sign "-" for the d and b in form (^o ' ", first line) insert in the special field before the field of ^o. Sign can also be inserted into the field for ^o, but in case of -1^o < d < 0^o in this field will be "0" and sign will be lost.

Ecliptic coordinates calculations is based on the current equator/ecliptic inclination angles ("E/El obl") with nutation calculation.

Galactic coordinates calculate with transition parametrs: North Galactic Pole equatrial coordinates (1950) a_N = 192^o.25, d_N = 27^o.4, Galactic longitude of ascess node on equator l₀ = 33^o.0.
