Define the jargons in the paper

[MaceKuailv]

There is a few jargons that are not explicitly defined in the paper. A few example include: ASF, SF_{LLL}, novel and blended SF.

For example, change
"...decomposition of longitudinal (along-r) and transverse (across-r) velocities, and data binning based on separation ..."
into
...decomposition of longitudinal (along-r, e.g. $SF_{LL},SF_{LLL}$) and transverse (across-r, e.g. $SF_{TT}$) velocities, and data binning based on separation ..."

I think staggered grid and curvilinear grid are worth mentioning in the paper or documentation. A quick search in the documentation also yields no results. Are they supported? It is totally fine if they are not supported. I am just being curious. Still, it is kind of important to let the readers know what kind of grids are supported.

P.S. It is a bit unlikely that I can get to the main software part this week. I'll try to make things move as fast as possible.
