    This product has been generated from Level 0 data collected when the instrument was in Image Mode. This product has lower resolution but higher radiometric resolution than the ASA_IMP.

    The product covers a continuous area along the imaging swath and features an ENL (radiometric resolution) good enough for ice applications..

    This product provides a continuation of the ERS-SAR image mode data.

    Spatial Resolution: 150 m ground range x 150 m azimuth
