5 What we have to do? To extract from raw data the spectra To clean the spectra To calibrate the RVS and the spectra To derive a Vr and eventually Vrot

6 The input list per object (with their uncertainties and quality flags) Astrometric parameters (CU3) RA and dec, proper motion for SolSYsObj Photometric parameter (CU5) magnitudes at the time of observation: from IDT CU3 or could be processed by CU5, variability from CU5/7 Classification parameters with their probabilities (CU8) param for selection of template (Teff, logg, Z) object class: solsysobj,qso, single star, binary, extended object etc. CU6 parameters-library inputs previous RVS data (internal CU6), synth data, cross-corelation masks, external standards (RV, spectro-photometric) CU6 inputs internal to CU6: what does it means?

7 CU6 inputs internal to CU6: what does it means? Daily processing: 1. spectroscopic processing raw data 2. IDT/ associated with spectro like sky mapper data daily transfer, and CU6 list as above, most recent calibration files Half-yearly processing: same Post mission end of processing: same

8 CU6 output Daily : updated calibration (instrumental) updated star calibrators new spectra faint star sanity radial and rotational velocities diagnostics calibration trends, triggers, alerts (from sanity) Half-yearly: update the stars calibrator status Post mission end processing: update the stars calibrator status

9 Traitments Multi-transit Analysis 1. Process data coming from the single transit: crosscorrelation products. Skew processing? 2. Multi transit spectral data analysis works on the individual spectra which could be shifted in wavelength space before co-adding.

10 Traitments Calibration/SGIS In daily calibrations, the model is updated. The SGIS occurs in a loop of 6 months?, the calibration of the parameters from the instrument are re-derived by refining both the calibration applied to the calibration of the star observations (reanalysis of the observations) and the model at the same time, iteration. (doc: GEPI/Gaia-RVS/TN/018.01) Size of the sample used by SGIS: affect the frequency of the re-run of the SGIS (Time between to consecutive SGIS run? In order to correct model for significant systematic effects)
