Dear Mario, Lino, Gert, Jelte and Jeffrey,<br>
<br>
I have added principle color plots, trilegal comparison and SDSS
comparison to the overview table: <br>
<pre wrap=""><a class="moz-txt-link-freetext" href="http://wiki.astro-wise.org/projects:kids:data_deliveries:kids-eso-dr1:release_notes:photometric_calibration#overview_table">http://wiki.astro-wise.org/projects:kids:data_deliveries:kids-eso-dr1:release_notes:photometric_calibration#overview_table</a></pre>
More in-depth report on it for release note is to follow soon.<br>
For most KiDS-ESO-DR1 OBs with SDSS DR8 coverage the difference is
within 0.05mag. If not it seems that in at least 30% of the cases it
might well be due to the usage of the "forever zeropoint" which was
defined in aug 2011. See extracted table from wiki:<br>

<pre wrap="">Dear Mario, Lino, Gert, Jelte and Jeffrey,
I've added the KiDS and SA field exposure timespan to the overview table:
<a class="moz-txt-link-freetext" href="http://wiki.astro-wise.org/projects:kids:data_deliveries:kids-eso-dr1:release_notes:photometric_calibration#overview_table">http://wiki.astro-wise.org/projects:kids:data_deliveries:kids-eso-dr1:release_notes:photometric_calibration#overview_table</a>
Gijs is making progress with principal color-color plots for stellar locus.
Mario is making SDSS comparison and trilegal comparison.
All info will be added to the overview as they come on-line.
Mario: please send me your results once ready: then we discuss together
how to add it to the overview.
Then we should have a good overview of photometric quality.
Best, Gijs

<pre wrap="">Dear Mario, Lino, Gert, Jelte and Jeffrey,
I have made and inspected an overview of the photometric quality of the
KiDS-ESO-DR1 nights according to Paranal (available for ~80%):
<a class="moz-txt-link-freetext" href="http://wiki.astro-wise.org/projects:kids:data_deliveries:kids-eso-dr1:release_notes:photometric_calibration#overview_table">http://wiki.astro-wise.org/projects:kids:data_deliveries:kids-eso-dr1:release_notes:photometric_calibration#overview_table</a>
Conclusion: except for one KiDS OB the data seem to have been taken
under (almost) photometric conditions.
As next step I will do the same check for the SA fields used for
KiDS-ESO-DR1.
Feedback on this and next steps is very welcome.
Best wishes, Gijs
ps. Lino: thanks for reminding of the existence of these plots. I had
seen them...but forgotten about them.
