<div class="moz-cite-prefix">Hello John!<br class="">
Sure, I hadn't understand before. Here are my object properties:<br class="">
<br class="">
R200: 1.00654482691 Mpccm/h<br class="">
Total Mass at R200: 3.65901447937e+14 Msun<br class="">
Avg Temperature at R200: 5.70273 E 7 K<br class="">
<br class="">
I tried decreasing the Area to 2000 but I'm still getting the
memory error.<br class="">
<br class="">
With a photons_per_chunk of: 10 E 6 I get:<br class="">
<font color="#666666" class=""> RuntimeError: Number of photons
generated for this chunk exceeds photons_per_chunk</font><br class="">
With an increase of 10 (10 E 7 photons_per_chunk) I get the same
Runtime error, but with an increase of 100 I get memory error!<br class="">
<br class="">
Again, observation parameters:<br class="">
A = 2000.<br class="">
exp_time = 100.0e3<br class="">
redshift = 0.05<br class="">
<br class="">
Do you have any idea on how could we solve this?<br class="">
<br class="">
Thanks for your time!<br class="">
<br class="">
