I'm sure there is a chance this subject has been brought up before..

But..

What is the difference?

Similar to the difference between Normal Sidereal/Normal Tropical?

Heliocentric = Sun at the centre, the light shining through the zodiacal band

Helio Sidereal = Sun at the centre, light shining through constellations in the sky.

Calculations vary.
