The Leveled. Data 



The first numerical task was to level the data using the equations derived 

 in Part 8. Missing data was a complicating factor. For the most part tiiis 

 was caused :'■ / 'iie presence of the ATLANTIS. The missing coordinates are

With missi'ig points in the data, there are two possible ways to level 



the data. One would be to minimize the sum of the squares of the deviations 



of the known values of the spot heights from an unknov/n tilted plane. The 



other would be to interpolate the unknown values irora the known data; 



use them in the equations given in Part 8j and level •iie data. The first
