    Dear JJ

  Could you please check the ingestion dates of the D_25 in ugri ands:
they have all been replaced last week and I checked them yesterday
morning. It may help if we had the ingestion date available so that
I could check them all at any time. I was with Fred when he did put
these files in the CADC replace area, so they should be ok.

    The D-85 has the wrong mag error again. Though we replaced them
a long time ago. I will check this with Fred.

    Chers
