4x5" transparency, Kodak calibration target

[artworker]

I'm an artist and I have a very big bunch of 4x5 transparencies (1,000) that were taken of my artwork for archive purposes.
They were all shot on Ektachrome Pro and developed using E-6.
Is your calibration target identified only as "4x5" transparency, Kodak" good for Ektachrome transparency stock?

Dear Customer,

our targets are also printed on Ektachrome.
Actually many of our customers use Ektachrome and it works just perfectly fine.

best regards and happy Christmas
