Coronal temperatures of the AGN ESO 103-035 and IGR 2124.7+5058 from
  NuSTAR observations
  We present measurements of the coronae of two AGN from hard X-ray
observations made with NuSTAR: ESO 103-035, a moderately to highly obscured
source with significant reflection; and IGR 2124.7+5058, a radio-loud source
with a very hard spectrum. Using an exponentially cut-off powerlaw model for
the coronal emission spectrum gives a high-energy cut-off of $100_{-30}^{+90}$
keV for ESO 103-035 and $80_{-9}^{+11}$ keV for IGR 2124.7+5058, within the
typical range for AGN. Fitting with physical Comptonisation models shows that
these correspond to a temperature of $22_{-6}^{+19}$ and $20_{-2}^{+3}$ keV
respectively. These values are consistent with pair production limiting the
coronal temperature.
