What is “absolute circular polarization fraction” for a pulsar?

[ZX.Liang]

In a pulsar paper, two terms were mentioned: circular polarization fraction and absolute circular polarization fraction.
1. What is the absolute circular polarization fraction?
2. What is the difference between them?

"Absolute" in that context would be the same as the absolute value of a number. For instance abs(-5) is 5, as is abs(5).

Another way of stating it is the 'distance' from Zero, regardless of whether it is above or below Zero.

For an example related to Pulsars, see Section 3 of:

(the above was the first hit of a Googles search:

Thank you.
I envy your freedom to use Google. It is illegal to use Google in our country.

Yes, different countries, and different politicians, load all of us with rules. Some are a good idea and some are not.

Stay Safe!
