AB: Using the Chianti database, we construct temperature response functions for the extreme ultraviolet and soft x-ray imaging channels on a variety of current and future solar observatories. Simulated observations in these channels are then inverted to recover the coronal differential emission measure. We investigate the effect of statistical error, and systematic uncertainties in the atomic physics and instrument calibration used to calculate the instrument temperature response functions, on the accuracy of the DEM recovery. By selecting different combinations of channels, we can characterize the ability of different instrument architectures to constrain the DEM, and identify an optimal combination of bandpasses for accurate DEM recovery.
