We\nobtained between 1020 and 1620 seconds exposure in the w filter. We calibrated\nour images against the APASS catalog. Our 10-sigma limiting magnitudes vary from\nw = 17.8 to 19.3.\n\nCompared to the USNO-B1, DSS DR2 and Pan-STARRS DR1 catalogs, we detect no\nuncataloged sources to our 10-sigma limit.\n\nWe thank the staff of the Observatorio Astronomico Nacional in San Pedro Martir.",
