<div class="elementToProof">The 'flux density' data taken Jan 31/Feb01 show occasional visibility drop-outs (meaning, the visibilities abruptly go to zero) for ea26, IF 'D'. The problem is occasional — less than 10% of the data are bad. The transition from
good to bad, or bad to good, is not related to the scans — it can happen in the middle of a scan. These bad data are not flagged by the on-line system.</div>
