This spectrum is the integration of all data for the scan with spectra from both polarizations added together. The spectral intensities are Ssys * (on - off) / off, where Ssys is the system temperature in Jy. The system noise flux density equivalent is calibrated for each scan with a calibration noise source firing during each scan. The cal value, in Jy, is calibrated by comparison with a number of continuum sources as described in the summary web page
This spectrum is the same as Figure 1 but with 22 60-second sub-integrations manually deleted because of interference or a bad baseline.
This is the section of spectrum measured to obtain the parameters listed below. The three horizontal dotted lines are the baseline, the peak level selected, and 20% of the peak level. The two vertical dotted lines mark the selected 20% line width edges. The solid horizontal line marks the velocity range chosen for the the line profile flux density integral. This spectrum has a second-order least squares fit baseline removed using most of the baseline shown in Figure 2.
Peak intensity: 0.005 Jy Lower 20% velocity: 5977.6 km/s Upper 20% velocity: 6638.8 km/s Systemic velocity: 6308.2 km/s Line width (20%): 661.2 km/s Profile integral: 2.89 Jy * km/s A: 4.15 B: 1.90 Ratio B/A: 0.457 Flux integral velocity range: 5921.3 - 6703.4 km/s
seems a likely detection, high velocity wing poorly defined
