|

| 8 | # Comment: stored values:
|
|---|
| 9 | # To compare satellite clocks provided by the two files, BNC first converts
|
|---|
| 10 | # coordinate differences dX,dY,dZ into along track, out-of-plane, and radial
|
|---|
| 11 | # components.
|
|---|
| 12 | # It then corrects the clock differences for the radial components of
|
|---|
| 13 | # coordinate differences. RMS values of clock differences are
|
|---|
| 14 | # finally calculated after introducing
|
|---|
| 15 | # - at first one offset 'per epoch for all satellites' and
|
|---|
| 16 | # - secondly one offset 'per satellite for all epochs'.
