starting situation

· Calibration status is updated once per year · User has no information between these updates what (s)he can expect · Cross cal document will have same frequency of updates

· Information flow is to slow and unclear ­ Should I wait for the new calibration to reprocess or not ?

idea - proposal

· Calibration (pre-)view tool
­ browse cross cal examples for various targets for
· actual SAS/Calibration · new upcoming versions --> Improving transparency of current calibration work

­ Giving expectation horizon ­ User will be able to judge if (near) future calibration will impact his analysis

Tool released · http://xmm.vilspa.esa.es/cgi-doc/ept/preview.pl · Using ESAC grid:
­ 10 nodes so far, each node has 2 CPUs Intel(R) Xeon(TM) 3.00GHz with 2GB of memory and hyper-threading ­ That reduces processing time by factor ~15-20 -->15-25 observations/hour ­ further speed up possible by · parallel fitting · enhancing data-caching on the grid

· Current content:
­ 234 observations ­ 50 ready to process

features
· · · website as the front end of the tool easy access the cross calibration data archive comparing joint and individual fits and their parameters and fluxes for various targets and observations concerning different calibration versions Features for every FIT (one table entry):
­ pop up and enlarge the spectrum ­ display the associated logfile

­ display the parameter (extraction of some values of the log file)

·

Features for every version (a whole column):

­ plot parameter over all versions this executes an IDL script, which plots all n parameter values of all cameras versus the versions. A pop-up shows the n plots ­ plot flux over all version a similar IDL script plots the flux in different energy ranges versus the versions. For every energy range one plot ­ Observation Log Browser executes the Observation Log Browser for the given observation id.

·

Second level data products regarding statistical flux comparison (only dev Marcus G. F. version)
