Method: Wcs.wcsconp

Defined in:

lib/wcs/libdoc.rb

.wcsconp(sys1, sys2, eq1, eq2, ep1, ep2, dtheta, dphi, ptheta, pphi) ⇒ [dtheta,dphi,ptheta,pphi]

Convert from coordinate system sys1 to coordinate system sys2, converting proper motions, too, and adding them if an epoch is specified

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)

• ep1 (Float) —

  Input Besselian epoch in years (for proper motion)

• ep2 (Float) —

  Output Besselian epoch in years (for proper motion)

• dtheta (Float) —

  Longitude or right ascension in degrees

• dphi (Float) —

  Latitude or declination in degrees

• ptheta (Float) —

  Longitude or right ascension proper motion in RA degrees/yea

• pphi (Float) —

  Latitude or declination proper motion in Dec degrees/year

Returns:

• ([dtheta,dphi,ptheta,pphi]) —

  • dtheta: Longitude or right ascension in degrees

  • dphi: Latitude or declination in degrees

  • ptheta: Longitude or right ascension proper motion in RA degrees/yea

  • pphi: Latitude or declination proper motion in Dec degrees/year
