phi
: the angle between the green vertical line passing through
the solar disk image and the violet radius vector "r" of the object
located at the center of the spectrograph slit - red cross
( positive - clockwise, negative - counterclockwise )
r : radius vector (in arcsec) of the object
located at the center of the spectrograph slit- red cross
P : position angle of the northern solar pole (as related to the
direction of the earth' axis)
sio : solar image orientation = diurnal movement
timezone : central european (summer) time
m. mirr. pos. = main mirror position - 0: in meridian,
E: to the east, W: to the west
mx : x coordinate of the coelostat main mirror
dec
: declination of the Sun
mz : distance of the two coelostat mirrors
x : carthesian solar coordinate alog axis parallel to solar equator (in arcsec)
y : carthesian solar coordinate alog axis parallel to solar axis (in arcsec)
