Notes for splinter meeting on photometric calibration in Astro-WISE.

Present:
Goranova
Koppenhoefer
Phleps
Pohlen
Radovich
Schmithuesen
Verdoes Kleijn
Wilman

Given the 20minutes of this meeting we limited ourselves to determining priorities:

*Standard star catalog
Version 9 will be released after the meeting with a release note.
Please give user feedback to Gijs Verdoes Kleijn.

*Illumination Correction
Yuliana Goranova has performed illumination corrections for WFI. 
Yuliana's expertise will be useful in fine-tuning the 
illumination correction procedure in Astro-WISE.

*Documentation photometric calibration algorithm
Gijs Verdoes Kleijn will put on-line a more detailed description of the photometric calibration algorithm.

*Background
The inaccuracies in photometric calibration of the background need to be quantified and their origin better constrained.

*Future discussions
Gijs Verdoes Kleijn will set-up a convenient way to discuss and share photometric calibration in Astro-WISE issues also after this meeting. This might be something like a wiki-page, user forum or mailing list.
