exdeq1

exdeq3 |
Calculate CXFUP matrix to prepare for Generalized Mis-tie Adjustment
(combined with Altitude Reduction from StdLIN line data by Equivalent
Anomaly method). The freedom of mis-tie adjustment is constrained to be
constant level for each line (exdeq1), linear variation for each
line (exdeq2), or arbitrary variation for each crossover point
(exdeq3). [In the process of exdeq3,
crossover points are searched for only between two line groups, traverse
and tie lines, where the line names starting with B,b,C,c,X,x are assumed
to be tie lines, and others traverses. The linear mis-tie variation
between adjacent crossover points is assumed.].

For the purpose of extracting magnetic anomaly change between repeated

method similar to exdeq3. [The freedom of
arbitrary adjustment is given to the crossover points but only for the
(one epoch) survey lines distinguished by the line names starting with
B,b,C,c,X,x. The linear mis-tie variation between adjacent crossover
points is assumed.]
