Dear All,<br class="">
at the last CalCom meeting, we started a discussion about the tools
we would like to have to manage constants in the calibration
database and perform actions such load or dump constants for
specific run ranges, list available variations, copy constants from
variations to variations etc. For CLAS this was done with scripts,
while for CLAS12 Gagik is proposing to extends the common tools in
order to do that. This requires the extension of the CCDB API
functionalities that we need to discuss with the CCDB experts. <br class="">
<br class="">
For this purpose, it was decided to dedicate one of the next CalCom
meeting to this topic inviting the Hall D CCDB experts in order to
hear from them how they have been doing this for GlueX, present our
work scheme and discuss the requests we may have. <br class="">
<u class=""><br class="">
In order to prepare for such meeting, we would like to ask
detector groups and calibrators to provide feedback on the kind of
tools and functionalities they would like to have to handle
calibration constants based on the work they have been doing and
past experience from working in CLAS or other experiments. </u>The
input you can provide will be important to develop a complete
workflow for the handling of calibration constants and come up with
a comprehensive lists of functionalities we need of have. <br class="">
<br class="">
Please send your input by replying to this email before next Friday,
August 5. We will discuss about it at the CalCom meeting.<br class="">
Best regards,<br class="">
Raffaella<br class="">
