Intensities in McStas are always 'per time-unit', i.e. a kind of flux. The normalization of course depends on what starting value of the neutron weight is assigned in the source component.</div><div><br></div><div>For further information, please consult chapter 4 in the McStas users manual.</div><div><br></div><div><br></div><div>Best regards,</div><div><br></div><div>Peter Willendrup</div><div><br></div><div><br></div><div><div><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>--<br>-------------------------------------------------------------------<br>Peter Willendrup - Development engineer<br><br>RISŲ DTU<br>Materials Research Division<br>Frederiksborgvej 399<br>DK-4000 Roskilde<br><br>Tlf.: (+45) 4677 5862<br>Mobil.: (+45) 2125 4612</div><div>Fax.: (+45) 4766 5758</div><div>Email: <a href="mailto:pkwi@risoe.dtu.dk">pkwi@risoe.dtu.dk</a></div><div>-------------------------------------------------------------------</div></div></span></div></span></div></span></span></div></div><div><br></div><div><br><div><div>On 04/11/2009, at 09.48, Genoveva Burca wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div marginleft="10" marginright="10" margintop="10" marginbottom="10" style="margin-left: 10px; margin-right: 10px; margin-top: 10px; margin-bottom: 10px; "><br><br><div align="left" style="text-align: left; "><font face="Arial" size="+0" color="#000000" style="font-family: Arial; font-size: 10pt; color: rgb(0, 0, 0); "> Dear all,</font></div><br><div align="left" style="text-align: left; "><font face="Arial" size="+0" color="#000000" style="font-family: Arial; font-size: 10pt; color: rgb(0, 0, 0); ">Could you please tell me what is being plotted on the PSD plots?
