We present a comparison of the velocity power spectra between the GOLF and MDI instruments. In addition, this poster outlines work towards creating a GOLF-simulated signal utilizing MDI velocity images. The simulation of the GOLF signal is achieved by integrating spatially weighted masks with MDI LOI-proxy velocity images. The GOLF-simulated signal and a selection of additional spatially masked MDI velocity signals are compared with the observed GOLF signal for a 759 day period from May 25, 1996 through June 22, 1998. Ultimately, a cross-analysis process between GOLF and MDI signals could lead to an enhancement of our ability to detect low frequency solar oscillations. The signal-to-background ratio (S/B) for the GOLF and the spatially masked MDI velocity data is presented for low degree (l <= 3) and low frequency p-modes. We find that signals from both MDI and GOLF are beneficial for detecting low degree (l <= 3) and low frequency (< 2000 mu Hz) p-modes. For the frequency range and the signals compared in this poster, the GOLF signal has the highest S/B for l=0 p-modes. The S/B of the GOLF and MDI central region masked signals is good for detecting l=1 p-modes. For l >= 2 p-modes, the central region masked signals have the highest S/B of the power spectra compared here. In addition, the S/B of the preliminary GOLF-simulated signal is found to be more similar to the GOLF signal than the MDI LOI-proxy signal without spatial masking for the modes investigated here.
