CTFFIND4 sometimes generates very large values for CTF fit resolution (e.g. 600-700Å) when it fails. These large values seem to break Curate exposures, because if I set and apply a threshold that should exclude them, it does not (e.g. see attached). The same seems to be true for negative CC values. Also, the text entry field only seems to allow one decimal place - if I enter a threshold of 0.03 for example, a threshold of 0 is applied.
Update: More generally (not just starting from CTFFIND input), if a bottom threshold is set to zero, the top threshold seems to be ignored, even if one clicks apply threshold. Negative and positive thresholds both work fine, but zero does not.
