/* The logic of processing ADES data to 80-column punched-card format is
somewhat convoluted. We have to take a possible mix of PSV and XML ADES
with 80-column data, plus possible extraneous text, and convert it to
a modified version of the MPC's format. The 'modification' is that
the times and RA/decs can be given to greater precision, and uncertainties
expressed with comment lines such as
COM Sigmas 0.5x0.4,0.93 m:0.02 t:0.5
to indicate RA sigma = 0.5 arcsec, dec simga = 0.4, that the correlation
between them is 0.93, magnitude uncertainty is 0.02, and the timing
uncertainty is 0.5 seconds. Note that the above comment can pass
through MPC's processing, but the actual information is left present
for Find_Orb and other software.
But it _does_ mean that a single PSV line may be output as two or
more lines (the above sigmas, and finally an 80-column astrometric
record). With XML, we have to read in many lines, gradually assembling
the sigmas and the 80-column output; only when we reach the closing
</optical> tag can we cough up two or more lines. If it's an MPC
line, we can pass it through unaltered... _unless_ it's a Dave Tholen
style 92-column line, with 80 "traditional" columns and sigmas in
the last twelve columns.
The above 'ades2mpc_t' context structure stores the various bits
of the output line(s). When we read a PSV line or hit the </optical>
XML closing tag, we set 'getting_lines' to 1, i.e., "we've got
the data we need; start outputting corresponding lines such as
the above comment and 80-column MPC data."
At that point, each call to xlate_ades2mpc( ) gets passed
along to get_a_line( ), which checks to see if we have some sigmas
or (for satellite observations) an object center or one or
(for satellite, radar, and roving observations) two 80-column
lines to be output. After we've done all that, 'getting_lines'
is reset to zero, and we're ready to accept the next observation(s). */
/* In theory, when we reach the end of the file, any 'state' flags that
got set (because of encountering ADES tags) should be cleared (because of
encountering closing tags). */
