WFC3 Notebook HTML previews are not properly loading

[FDauphin]

@mackjenn has noticed that several of WFC3 notebooks' outputs have been cleared (an example is shown here. Any idea of what might have caused it? Maybe something happened after the last notebook (zeropoints #114) was merged?

Thank you for letting me know. All notebooks are executed/rerun on a weekly basis. If a notebook fails during this process, it will not generate any outputs on the HTML page. In such cases, the notebook needs to be evaluated to fix the issue. @dulude and/or @mgough-970 might have already contacted the authors/curators to inform that about the problems.

HTML files worked via communications with @mackjenn; closing issue.
