! Description:
! Curves are identified as follows: 
! Celestial equator:    equ
! Ecliptic:             ecl
! Tropic of Cancer:     cancer
! Tropic of Capricorn:  capr
! Other curves are labeled as <latitude><label>, with <latitude>
! the geographic latitude in the format DDMM (degrees,minutes) and
! <label> defined as follows:
! NOTE: NO CORRECTION FOR ATMOSPHERIC REFRACTION WAS INCLUDED IN THE CALCULATIONS.
! <latitude>.ast   astronomical twilight (sun 18 degr. below horizon, NO refraction!)
! <latitude>.nau   nautical twilight (sun 12 degr. below horizon, NO refraction!)
! <latitude>.ast   civil twilight (sun 6 degr. below horizon, NO refraction!)
! <latitude>h0     elevation 0 degrees above horizon (i.e. the horizon)
! <latitude>h10    elevation 10 degrees above horizon etc. etc.
! <latitude>A0     Azimuth 0 (North, is a straight line, as is Azimuth 180)
! <latitude>A10    Azimuth 10 degrees etc. etc.
! Coordinate grid x,y defined as North celestial pole at (0,0), North horizon at the bottom.
! Scale: equator is a circle around (0,0) with radius 100.
