Method: Wcs.wcscon

Defined in:

lib/wcs/libdoc.rb

.wcscon(sys1, sys2, eq1, eq2, dtheta, dphi, epoch) ⇒ [dtheta,dphi]

Convert between coordinate systems and equinoxes

Parameters:

• sys1 (Integer) —

  Input coordinate system (J2000, B1950, ECLIPTIC, GALACTIC)

• sys2 (Integer) —

  Output coordinate system (J2000, B1950, ECLIPTIC, GALACTIC)

• eq1 (Float) —

  Input equinox (default of sys1 if 0.0)

• eq2 (Float) —

  Output equinox (default of sys2 if 0.0)

• dtheta (Float) —

  Longitude or right ascension in degrees

• dphi (Float) —

  Latitude or declination in degrees

• epoch (Float) —

  Besselian epoch in years

Returns:

• ([dtheta,dphi]) —

  • dtheta: Longitude or right ascension in degrees

  • dphi: Latitude or declination in degrees
