A small portion of the label is written in IBM binary code and will not be properly converted using LABEL.
The VICAR label is also preserved in NEWSIPS files. The EBCDIC information however is converted to ASCII and stored as commentary keywords in the FITS header. Image processing information is stored in FITS ``HISTORY'' keywords, which are considered part of the label by our programs. The LABEL program can be used to extract the label from the FITS header and is a useful tool for identifying the contents of a NEWSIPS FITS file. The display will look nearly identical to that produced when reading an IUESIPS file except that lines originally containing binary data now appear as two lines containing hexadecimal ASCII characters. This should not worry the user as the doubled binary lines will not be assigned independent line numbers. Thus line 101 will still be the first line of the processing history. Examples of using LABEL to display information in the IUE science image header file are given in Table 3.3. Remember that 'IMAGET' assumes the file extension is specified for NEWSIPS FITS files but not for IUESIPS RDAF-format files.
