Unlike MCUBE, which tries to be very general, FQUBE only works with image cubes with a FREQ or FQID axis and builds a cube with an FQID axis. FQUBE does not handle subimages at all - the images must match in terms of the number of pixels on each actual axis ignoring the FQID or FREQ axes. If DOALIGN > -2, the actual axes must match in more detail. In some ways, FQUBE is like running MCUBE with the DOCONCAT option but it should be simpler to use when building a frequency axis that is not regularly gridded. Task SPIXR will analyze such cubes to fit images of spectral index. A task to do "rotation-measure" synthesis is under development and requires such cubes as input. Adverbs: INNAME......Input name of images(name). Standard defaults. Must be the same for all input images. INCLASS.....Input name of images(class). Standard defaults. Must be the same for all input images. INSEQ.......First seq no. of the images. 0 => highest. INDISK......Disk drive # of images. 0 => any. May vary between images if INDISK is set to 0. IN2SEQ......Last sequence # in set of input images. No default. IN3SEQ......Sequence # increment. 0 => 1. Thus, FQUBE uses sequence numbers INSEQ to IN2SEQ by IN3SEQ in the usual loop sense. OUTNAME.....Output name of image(name). Standard defaults. OUTCLASS....Output name of image(class). Standard defaults. OUTSEQ......Output name of image(seq. #). 0 => highest unique. OUTDISK.....Disk drive # of output image. 0 => highest with space. DOALIGN.....Controls how the images are to be aligned on axes 1 - n-1 (see HELP DOALIGN). True (>.1) means that the images must agree in their coordinates including the reference pixel. DOALIGN > -2 means that the actual axes must agree on the coordinate name but the output coordinates are taken from the first input image. DOALIGN = -2 means that the images must agree only in the number of pixels on each non-frequency axis. Use SUBIM to reduce images to a size that matches and/or OHGEO or HGEOM to re-grid images onto matching coordinate systems. ----------------------------------------------------------------
