Upper panel: histogram of the magnetic field modulus for all 238 Ap stars with resolved, magnetically split lines. The new additions from SDSS/APOGEE are shaded in green. Lower panel: comparison of ﹩\langle B\rangle ﹩ as measured in the H-band vs. the optical. The dashed line indicates perfect agreement.
