The normalization of the 2d sky subtracted points in SuNNS seems to be off by approximately 20%. The rerun is placed at /projects/HSC/PFS/Subaru/rerun/ncaplar/<a href="https://pfspipe.ipmu.jp/jira/browse/PIPE2D-857" title="Apply sky subtraction, deduced from DCB to SuNNS data, for limited number of fibers" class="issue-link" data-issue-key="PIPE2D-857"><del>PIPE2D-857</del></a>_SuNSS . As Paul mentioned during the Monday meeting (Jun 28), there is a possibility that this is a simple bug due to recent refactoring of normalization and psf flux measurements.</p> PIPE2D-866

The main problem was that the line photometry was being done with the temporary PSF while the subtraction was being done with the proper PSF.</p> <p><span class="image-wrap" style=""><img src="https://pfspipe.ipmu.jp/jira/secure/attachment/13943/13943_subtraction.jpg" style="border: 0px solid black" /></span></p> <p>Changes are fine.
