There has been a long-standing discrepancy between the measured values of galaxy-QSO cross-correlations and the expected values from models of gravitational clustering. Part of this discrepancy has been due to the simplicity of early models that determined the expected cross-correlations while assuming a particular shape to the mass power spectrum. A more complete approach that utilizes the halo model and includes galaxy biasing works toward resolving a portion of the discrepancy, but it does not resolve it completely. As a result, we estimate the impact of systematic effects such as dust extinction and catalogue selection functions in the measurement of galaxy-QSO cross-correlations on angular scales of one degree by directly comparing the cross-correlations that are derived from different combinations of galaxy and QSO data sets.
