+	S_WTYPE		# the projection type
+	S_PLNGAX	# the physical ra / longitude axis
+	S_PLATAX	# the physical dec / latitude axis
+	S_XLAX		# the logical ra / longitude axis
+	S_YLAX		# the logical dec / latitude axis
+	S_PIXTYPE	# the IRAF pixel coordinate system type

+DESCRIPTION
+Sk_stati returns the values of integer sky coordinate descriptor parameters.
+

+NOTES
+Permitted values of S_CTYPE are CTYPE_EQUATORIAL, CTYPE_ECLIPTIC, 
+CTYPE_GALACTIC, and CTYPE_SUPERGALACTIC. The corresponding string dictionary
+is CTYPE_LIST.
+
+Permitted types of S_RADECSYS are EQTYPE_FK4, EQTYPE_FK4NOE,
+EQTYPE_FK5, EQTYPE, ICRS, and EQTYPE_GAPPT. The corresponding string
+dictionary is EQTYPE_LIST.
+
+Permitted values of S_WTYPE are WTYPE_LIN, WTYPE_AZP, WTYPE_TAN,  WTYPE_SIN,
+WTYPE_STG, WTYPE_ARC, WTYPE_ZPN, WTYPE_ZEA, WTYPE_AIR, WTYPE_CYP, WTYPE_CAR,
+WTYPE_MER, WTYPE_CEA, WTYPE_COP, WTYPE_COD, WTYPE_COE, WTYPE_COO, WTYPE_BON,
+WTYPE_PCO, WTYPE_GLS, WTYPE_PAR, WTYPE_AIT, WTYPE_MOL, WTYPE_CSC, WTYPE_QSC,
+WTYPE_TSC, WTYPE_TNX, WTYPE_ZPX. The corresponding string dictionary is
+WTYPE_LIST.
+
+Permitted values of S_PIXTYPE are  PIXTYPE_LOGICAL, PIXTYPE_TV,
+PIXTYPE_PHYSICAL.  and PIXTPE_WORLD. The corresponding string dictionary
+is PIXTYPE_LIST.
+
+Permitted values of S_NLNGUNITS are SKY_HOURS, SKY_DEGREES, and SKY_RADIANS.
+The corresponding string dictionary is SKY_LNG_UNITLIST.
+Permitted values of S_NLATUNITS are SKY_DEGREES, and SKY_RADIANS.
+The corresponding string dictionary is SKY_LAT_UNITLIST.
+
+The parameters S_CTYPE, S_RADECSYS, S_NLNGUNITS, and S_NLATUNITS are
+important for all sky coordinate descriptors regardless of the source.
+The parameters S_WTYPE, S_PLNGAX, S_PLATAX, S_XLAX, S_YLAX, S_PIXTYPE,
+S_NLNGAX, and S_NLATAX are only important for sky coordinate descriptors
+derived from an image sky coordinate systems. S_STATUS is OK if the sky
+coordinate descriptor describes a valid celestial coordinate system, ERR
+otherwise.
