Noise/band Figure

Hi Josquin,

Are those units correct? uK-arcmin is a noise density (map noise with pixels 1 arcmin in diam, hence pixel area 1 arcmin^2). Dividing this by the beam FWHM in arcmin gives the noise density per beam (uK/beam), which can then be transformed to units Jy/beam using the usual conversion from thermodynamic temperature units to Jy. That would suggest changing the Y-axis labels from Jy/sr to Jy/beam.

But that makes it harder to compare between channels, or between PICO and other experiments, since everything on the plot would then be referred to the specific PICO beam widths. I'd prefer leaving the units Jy/sr and performing the conversion from arcmin pixelization to steradians. This allows simpler interpretation for any choice of beam.
