Step to reproduce:
Go to Firefly tri-view, make a search of WISE image on Single exposure ('4 band level1') and band 2. The image doesn't show up and error is thrown in the tomcat ouput.
(Unit tests regarding the FITS package have been failing lately too which is an indication of something broken in general with FITS reader)

so per the document, 'continue.pdf', keyword LONGSTRN is recommended. As long as '&' and CONTINUE appears, it should be treated as long string no matter if LONGSTRN exists and where LONGSTRN is located in the header?
A pointer to the definition of the long-value convention in FITS files:
https://fits.gsfc.nasa.gov/registry/continue/continue.pdf
Note the clarification to one thing we were talking about yesterday: if a line containing a keyword value ending in "&" is not immediately followed by a CONTINUE line, the above standard says that the ampersand is to be treated as part of the keyword value (instead of being deleted). This rule would apply to the Herschel files that we looked at yesterday. Whether that is what the Herschel team intended when they wrote those files is another question.
