+There are two commands useful 
+when analyzing large catalogs (BINARY\_TBL) in FITS format, which avoid reading the whole
+table in memory. {\tt swfitstable}\myppageref{swfitstable} reads a specified HDU 
+as a {\bf SwFitsDataTable} object which uses the FITS file as swap space.
+The {\tt fitsadapt}\myppageref{fitsadapt} can also be used for similar purposes.
+
+The following commands shows how to open a FITS file containing a synchrotron map
+of our galaxy:
+\begin{verbatim}
+#  Open the fits file : the map is in HEALPix format
+readfits syncmap.fits
+#  Create a window with the appropriate size
+newwin 1 1 800 400
+# Display the map, specifying the colormap
+disp syncmap 'lut=lin,2,50 midas_bluered'
