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 9 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. Narrow band interference was removed from 4 channels by interpolation between the nearest valid channels
Peak intensity: 0.010 Jy Lower 20% velocity: 6125.1 km/s Upper 20% velocity: 6689.2 km/s Systemic velocity: 6407.1 km/s Line width (20%): 564.0 km/s Profile integral: 2.56 Jy * km/s A: 1.60 B: 2.55 Ratio B/A: 1.594 Flux integral velocity range: 6099.3 - 6720.6 km/s
