These are covariant basis vectors.
They are arranged in a row matrix.
Their indexes are in the lower position.

So remember that.

Co. Row. Low.

I'll take vectors in non projected space for 1,000, Alex.

If it were up to me, I'd say introduce Japanese quotation marks to indicate the presence of an index.

So, they are elements of a cotangent space.
Got it.
