Thank you. I gave up on using prime, it's not a good notation anyway. For the record I'll leave here the tests I did.
I wanted alternatives 6, 7, 11, 12 but could not do it in context. Alternatives 15, 21 are almost there, but the prime is clearly smaller than the ones in 13, 19, and too small imo.

plain tex:

$$1T\prime + 2T^\prime + 3T\prime_{rs} + 4T_{rs}\prime + 5T^{{}^\prime}_{rs} + 6T_{rs}^\prime + 7T^\prime_{rs}$$

$$8T' + 9T^{'} + 10T^{'}_{rs} + 11T'_{rs} + 12T_{rs}' $$


context:

\starttext
\startformula
13T\prime + 14T^\prime + 15T\prime_{rs} + 16T^\prime_{rs} + 17T_{rs}\prime + 18T_{rs}^\prime
\stopformula

\startformula
19T' + 20T^' + 21T'_{rs} + 22T^'_{rs} + 23T_{rs}' + 24T_{rs}^'
\stopformula
\stoptext

Hi
is there a way for \prime not get smaller when used with sub/superscripts?
Or realigned somehow? Without font changes would be nice.

\starttext

\startformula
\frac13T\prime_{rs}T\prime_{st}T\prime_{tr}
\stopformula

\startformula
\frac13T_{rs}\prime T_{st}\prime T_{tr}\prime
\stopformula

\stoptext

I always thought that one was supposed to use either

   T' or T^{\prime}

So, if you want a bigger prime symbol, that is really a font design issue.

Having said that, I believe that it should be possible to control the scaling of the prime using a font goodies file, but I do not know the details.
