Is the static dielectric tensor given in cartesian coordinates in real space?

Dear all,
I have a question concerning the static dielectric tensor ( INCAR: LEPSILON = .TRUE.) .
In the OUTPUT file the static dielectric tensor is written after below heading:
HEAD OF MICROSCOPIC STATIC DIELECTRIC TENSOR (INDEPENDENT PARTICLE, excluding Hartree and local field effects)
------------------------------------------------------
7.750898 0.000000 -0.005793
0.000000 7.748910 0.000000
-0.005804 0.000000 5.882622
------------------------------------------------------
What is the basis of this tensor?
Is it given in cartesian coordinates or in lattice vector basis in real or reciprocal space?
Thank you in advance for the solution.
Best regards,
Tomasz Woźniak
