HCO+/SPW 21 has some bad baseline fits

[SpacialTree]

For the Weblog QA, the only step with a lower QA score was (13) hsd_imaging, which was due to a high percentage (~0.03%) of masked pixels.

[SpacialTree]

The baseline RMS image for spectral window 21 has an odd circular feature in the bottom right, likely related to the bad baseline fit mentioned above.

The masked average spectrum of spw 21 shows a bad baseline, too.

Should there be a continuum image? I'm going to assume that was erroneously added to the checklist.

Spw 17. The first and last channels are higher than the baseline for some reason. Otherwise, the cube looks fine.

Spw 19. Again, the first and last channels are oddly high compared to the baseline.

A zoom-in of the baseline shows that it varies periodically, maybe a baseline ripple?

Spw 21. As expected from the baseline issues mentioned before, the baseline of this cube is messed up. There is a negative bowl here, at the same location as the RMS feature.

Spw 23. There is also a negative feature here, in the same location as the negative bowl in Spw 21.

Spw 25. The baseline is very rippled for this spectral window. Note: When first opening the cube, it seems empty, like there are empty channels at the start of the cube.

There is a spectral line hidden in the noise.

Spw 27. Similar to Spw 25, the baseline looks like it has a ripple, but it seems rich with lines hidden in the noise. Note: When first opening the cube, it seems empty, like there are empty channels at the start of the cube.
