+NAME
+sklltran -- apply pm and transform between coordinate systems
+.ih
+SYNOPSIS
+call sk_lltran (incoo, outcoo, ilng, ilat, ipmlng, ipmlat, px, rv, olng, olat)
+
+.nf
+pointer	incoo		# the input sky coordinate descriptor
+pointer	outcoo		# the output sky coordinate descriptor
+double ilng, ilat	# the input sky coordinates in radians
+double ipmlng, ipmlat	# the input proper motions in radians  / year
+double	px		# the input parallax in arcsec
+double	rv		# the input radial velocity in km / sec (+ve receding)
+double olng, olat	# the output sky coordinates in radians
+.fi
+.ih
+ARGUMENTS
+.ls  incoo    
+The input sky coordinate descriptor.
+.le
+.ls  outcoo    
+The output sky coordinate descriptor.
+.le
+.ls ilng, ilat
+The input sky coordinates in radians.
+.le
+.ls ipmlng, ipmlat
+The input proper motions. For these to be applied the input coordinate
+system must be an equatorial coordinate system. If proper motions are
+unknown do not set ipmlng and ipmlat to 0.0, use sk_ultran instead. Note that
+the ra proper motion is in dra  not cos (dec) * dra units.
+.le
+.ls px
+The parallax in arcseconds. Use 0.0 if the proper motion is unknown unknown.
+The parallax value is used only if proper motions are defined.
+.le
+.ls rv
+The radial velocity in km / sec. Use 0.0 if the radial velocity is unknown.
+The radial velocity value is used only if proper motions are defined.
+.le
+.ls olng, olat
+The onput sky coordinates in radians.
+.le
+
+.ih
+DESCRIPTION
+The coordinates in the input sky coordinate system are converted to
+coordinates in the output sky coordinate system.
+.ih
+NOTES
+If the proper motions are undefined use the routine sk_ultran. Zero valued
+proper motions are not the same as undefined proper motions.
