| 10 | # in case of "single epoch" and "filter" combination
|
|---|
| 11 | # - residuals per satellite and AC
|
|---|
| 12 | # - resultant combined clock correction in [seconds]
|
|---|
| 13 | # - full clock in [m]
|
|---|
| 14 | # additional for "filter" combination
|
|---|
| 15 | # - estimated clock offset common for all satellites of a system and one AC
|

| 16 | # - estimated clock offset per satellite and AC
