16 Problème les 12, 13, 14 Novembre ?

17 Problème Lumière parasite LOS_ALT = -106 par ex sur des images HMP complètes ?

18 Limb analysis (C.Grec) N1 HL files ; - Images : not the right flat-field - Header : Rsun value was not right  - Procedure to determine Rsun - 2-D filter to estimate the positions of the inflexion points. - Fit of an ellipse to these estimates.

19 Elliptical fit of the inflexion points; minor and major axis

20 Maximal width of the inner annulus

21 Sun center – Mask center

22 Conclusions We just begin to explore the sources of photometry perturbation : need to identify all operational sequences signatures. Several calibration problems and definition of the key-words in the N1: we really NEED N0 access to be able to progress. Reprocessing ? (with the right flat-field) First l-nu diagrams: a real pleasure (first), and encouraging.

23 Messages for CS: - access to low level data: decision about the requests already done. -validation groups: definition and strategy. -Reprocessing: policy And a lot of work in front of us !

24 Actions: -HKs spectra -Check data products (Headers, time sampling/stamping …) -6-day or not in the Rsun ? -Operational visualisation (SAA…) -Recenter the HELIO mask ?
