The sensitivity map looks fine but reconstructed images make no sense. We think that there would be a problem regarding to castor ID for each detector (but we are not fully sure).<br class="">We currently create a binary LUT file as the for loops (*1) suggested in the document. Does the castor ID for detectors follow the order like (*2)?<br class=""><br class="">Any suggestions/comments are welcome.<br class=""><br class="">Thank you and kind regrads,<br class="">Daiki Hayakawa<br class=""><br class=""><br class="">(*1)<br class="">for(iLayer=0;iLayer<NLayer;iLayer++)<br class=""> for(iRing=0;iRing<NRing;iRing++) <br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>for(iDet=0;iDet<NDet;iDet++) { <br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>fwrite(&Posx[iLayer][iRing][iDet],sizeof(FLTNBLUT),1,fPtr); <br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>fwrite(&Posy[iLayer][iRing][iDet],sizeof(FLTNBLUT),1,fPtr);<br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>fwrite(&Posz[iLayer][iRing][iDet],sizeof(FLTNBLUT),1,fPtr);<br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>fwrite(&OrVx[iLayer][iRing][iDet],sizeof(FLTNBLUT),1,fPtr);<br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>fwrite(&OrVy[iLayer][iRing][iDet],sizeof(FLTNBLUT),1,fPtr); <br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>fwrite(&OrVz[iLayer][iRing][iDet],sizeof(FLTNBLUT),1,fPtr); <br class="">} <br class=""><br class="">(*2)<br class="">for(iLayer=0;iLayer<NLayer;iLayer++)<br class=""> for(iRing=0;iRing<NRing;iRing++) <br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>for(iDet=0;iDet<NDet;iDet++) { <br class=""><span class="Apple-tab-span" style="white-space:pre"> </span>castorID = iDet + iRing*NDet + l*NRing*NDet;<br class="">}<br class=""><br class=""><div class="">
