Velocity and acceleration for the positions of the sun meridian declination, according to the geometric model

The data set gives the sun meridian declination for every day of the year, according to the geometric model for the sun declination. In the next columns, the velocity and acceleration of the sun meridian declination is also assessed. And the last column assesses the relative concentration of solar resources available per minute of latitude (arcmin), which is obtained by giving 100% to the 365 rotations of the planet, considering the velocity of the sun meridian declination.
