<div dir="ltr"><div>Hi, Harald--</div><div><br></div><div>If you make a projection like this:<br>>>> proj = pf.h.proj(0,'Density')<br><br></div><div>then proj has most of the quantities you want. <br><br></div>
<div>>>> proj['Density']<br><br></div><div>will give you a flat array of the density in the 2d projection.<br></div><div><br>>>> proj.keys()<br>['pdy', 'pdx', 'weight_field', 'px', 'py', 'Density']<br>
<br></div><div>here, 'pdx' and 'pdy' are the half-widths of the zones, 'px' and 'py' are the positions of the zone centers<br></div><div><br></div><div>It also will get projections that you haven't already done. For instance, proj['x-velocity'] will make a projection of the x-velocity, then return the array.<br>
<br></div><div>I don't know if you can stick it into BinnedProfiles, but since the arrays are 2d, I always just make my own binning loop, I find it fast enough even on pretty big datasets. <br><br></div><div>I hope that helps,<br>

<br>
I'd like to do some analysis on projected quantities (or column densities) and quantities derived from those, like ratios etc.<br>
How can I use the output of some projections to derive some other quantities from it?<br>
How can I use those as inputs for BinnedProfileXd()-stuff, to compute profiles and phase plots?<br>
This would be extremely useful for analyzing my disk galaxy simulations.<br>
<br>
Thanks for your help.<br>
<br>
Best.<br>
