.help skstati Mar00 Skywcs .ih NAME skstati -- get an integer sky coordinate descriptor parameter .ih SYNOPSIS include ival = sk_stati (coo, parameter) .nf pointer coo # the input sky coordinate descriptor int parameter # the integer parameter to be returned .fi .ih ARGUMENTS .ls coo The sky coordinate descriptor. .le .ls parameter Parameter to be returned. The integer parameter definitions in skywcs.h are: .nf S_CTYPE # the celestial coordinate system type S_RADECSYS # the equatorial system type S_NLNGUNITS # the ra / longitude units S_NLATUNITS # the dec/ latitude units 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 S_NLNGAX # the length of the ra / longitude axis S_NLATAX # the length of the dec / latitude axis S_STATUS # the coordinate system status .fi .le .ih DESCRIPTION Sk_stati returns the values of integer sky coordinate descriptor parameters. .ih 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. .ih SEE ALSO skstatd, skstats .endhelp
