Version 2.11.3
The STDADS/TABLES package can read directly FITS binary tables. Information about the table can be obtained with the commands tinfo and tlcol.

The FITS tables can be converted into images for further use in IRAF (e.g. splot) with other STSDAS/TABLES commands such as titable and tomultispec.
The bi-dimensional SILO files can be read with RFITS:
cl> rfits swp03558.silo 0-1 data
File: swp03558.silo -> data0000.imh size=640x80
bitpix=16 bscale=0.03125 bzero=0. pixtype=real
Extension: 1 IMAGE -> data0001.imh size=640x80
bitpix=16 scaling=none pixtype=short
This is the SILO image:
cl> imhead data0000 l+
data0000[640,80][real]:
No bad pixels, min=-603.875, max=258.125
Line storage mode, physdim [640,80], length of user area 13933 s.u.
