... Special problems arise with filters intended to measure red leaks in blue and ultraviolet filters. ... The column named REDLEAK contains an 8-character string that specifies the treatment of red leaks in short-wavelength filters. Possible values are 'MEASURED' if the red leak is measured by observations through a filter that isolates the leak; 'BLOCKED' if a copper-sulfate or other blocking filter is used; or 'IGNORED' if the leak is neither measured nor blocked. ...
