Fixed and movable longitude:

Movable longitude is the zodiac longitude of a heavenly body calculated from the vernal point

To get the Fixed longitude, you must subtract Ayanamsa to movable longitude.

This is a necessary correction to get zodiac sign the same as the constellation of the same name.

For example, if you don't subtract Ayanamsa a planet in Virgo his in fact in Leo constellation.

Notice that Hindus always use Fixed longitude.
