27. Summary
The raw data collected during the observation trip will be analyzed
The calibration sources did not show any signal above the noise. This may indicate that the noise level is at least 203 JY which was the highest signal calibration source attempted. (3C274)
The one galaxy (NGC5457) observation did not appear per the observation guide.
A number of unknown signals were present that were not in the guide – these will be added and researched to determine their identification

28. Summary
A drift scan across Milky Way through SAG A* appeared to be show the edges of the Milky Way and the approximate location of SAG A*
Measurements were taken at different Galactic Longitudes to calculate the Galactic rotation rate. The Doppler shift of each point will be determined. The rotation rate is based on Doppler (km/second) and source location. The results will be calculated and briefed at next science meeting.
This was an excellent observation trip!
