+$a$: all information on bonds, spots or collections or records of observations
+$dim_a$: dimension of bonds
+$y$: Observation vector, List of observation values
+$dim_y$: dimenension of obs
+$is$: Ispace, Interpolation space, list of interpolation points and variables
+$dim_i$: dimension of interpolation space
+$y-i-list$: values needed for y from $is$, this is a vector of some dimension $dim_{yi}$, referenced by vectors yii and yil of integers, where yii(jy) is the starting index and yil(jy) is the number of points needed for the observation with index jy.
