Comment by Howard Bushouse: [~htran] Please indicate where the data sets can be found, in order for us to triage the problem.

Comment by Catherine Kaleida: We will be running the nOps7 data on the D-string, at which point [~bushouse] will investigate.

[stscijgbot]

Comment by Hien Tran: This error is no longer seen in the reprocessing of nops7 data on the A-string with B7.5

Comment by Howard Bushouse: Thanks [~htran] for the report. Will close the ticket, since this seems to have been resolved in B7.5.
