| * **Script changes:** Have changed the recorder to throw out traces from the spectrum analyzer that do not have the expected length - this simplifies data reduction as these traces would need to be removed prior to analysis normally. | * **Script changes:** Have changed the recorder to throw out traces from the spectrum analyzer that do not have the expected length - this simplifies data reduction as these traces would need to be removed prior to analysis normally. | ||
| - | * ** data reduction:** Track from Jan 21 has been reduced and didn't seem to have many issues (other than incomplete traces) - off source scans with the 3 degree offset still have signal in them and therefore power levels are underestimated. Jan 22 data seems to have a little bit of signal still in the band unfortunately - not sure if its worth going to 5 degrees. Something seems to have happened in the second half of the track on Jan 22 - looks like L1 and L2 signal disappear completely after a certain time. Perhaps there was a windstow I missed, I will check the logs on newsmerd. | + | * ** Data reduction:** Track from Jan 21 has been reduced and didn't seem to have many issues (other than incomplete traces) - off source scans with the 3 degree offset still have signal in them and therefore power levels are underestimated.
