INCLASS Image name(class). INSEQ 0.0 9999.0 Image name(seq. #). 0=>high INDISK 0.0 9.0 Disk drive #. 0 => any. ---------------------------------------------------------------- ALTSWTCH Type: Verb Use: After ALTDEF has been used to define a relationship between frequency and spectral-line velocity, the user may select one or the other to be the main image header description of the relevant axis. This description will be used by axis labeling and other display routines. ALTSWTCH switches the header between the two descriptions. Adverbs: INNAME......Image name(name). Standard defaults. INCLASS.....Image name(class). Standard defaults. INSEQ.......Image name(seq. #). 0 => highest. INDISK......Disk drive # of image. 0 => any. ----------------------------------------------------------------
