Examples of the flux re-calibration based on SDSS photometry for CGC071-96 (observed with the V300 grating, top panel) and CGCG430-046 (V600 grating, bottom panel). The values for the SDSS g and r filters used in the re-calibration are presented with blue solid circles, as well as the derived values for SDSS u and i filters. Johnson B,V, and Cousin R_C magnitudes are also shown (red solid squares) to test the flux calibration.
