The flux of the best-fit model was scaled using the broad-band photometry (<a href="https://pfspipe.ipmu.jp/jira/browse/PIPE2D-838" title="Absolute scaling of the best-fit model spectrum" class="issue-link" data-issue-key="PIPE2D-838"><del>PIPE2D-838</del></a>). It is distributed around 1. There is a systematic offset in the blue part at ~400 nm. This comes from stellar typing. In this case, the simulated spectrum was generated at Teff=7000K, logg=4.5, <span class="error">[Fe/H]</span>=0, <span class="error">[a/Fe]</span>=0, while the best-fit parameters are Teff=7069K, logg=3.69, <span class="error">[Fe/H]</span>=-1.5, <span class="error">[a/Fe]</span>=0.6. </p> <p><span class="image-wrap" style=""><a id="13945_thumb" href="https://pfspipe.ipmu.jp/jira/secure/attachment/13945/13945_vector.png" title="vector.png" file-preview-type="image" file-preview-id="13945" file-preview-title="vector.png"><img src="https://pfspipe.ipmu.jp/jira/secure/thumbnail/13944/_thumb_13944.png" style="border: 0px solid black" /></a></span></p> <p>This is a resultant flux calibration vector of the above case. The flux calibration vector is a ratio of the best-fit model spectrum to the input spectrum. Here, the atmospheric absorption and the quartz flat were applied to the input spectrum. </p> <p><span class="image-wrap" style=""><a id="13945_thumb" href="https://pfspipe.ipmu.jp/jira/secure/attachment/13945/13945_vector.png" title="vector.png" file-preview-type="image" file-preview-id="13945" file-preview-title="vector.png"><img src="https://pfspipe.ipmu.jp/jira/secure/thumbnail/13945/_thumb_13945.png" style="border: 0px solid black" /></a></span></p> Blocks PIPE2D-371 PIPE2D-373 PIPE2D-838 Development Rank 0|02qptg:h Reviewers hassan Story Points 4.0
