I'm not sure what does that mean? Any ideas? Is this related to the
small photon list I'm working with? <br class=""></div></div></blockquote><div><br class=""></div>This is a bug I fixed yesterday—when I have some way of getting the patch to you I will let you know. </div><div><br class=""><blockquote type="cite" class=""><div class=""><div bgcolor="#FFFFFF" text="#000000" class="">
I have increased the observation redshift from 0.01 (as in the
example) to 0.07 because I was obtaining another error that said: <br class="">
<br class="">
<font color="#666666" class="">585 fak = Aratio*Tratio*Dratio<br class="">
586 if fak > 1:<br class="">

589 <br class="">
<br class="">
ValueError: Spectrum scaling factor = 8.78099, cannot be greater

But I'll admit I fixed that purely by chance and playing with the
parameters... <br class=""></div></div></blockquote><br class=""></div><div>This happens when you choose parameters for project_photons that would result in a higher number of photons being drawn than exist in the original set that you generated.
