1. Cluster Active Archive Science User Working Group (CAASUWG) - update Matt Taylor on behalf of CAASUWG

2. CAASUWG- who? CAASUWG set up to provide forum for science users to comment on and /or suggest possible improvements of their CAA experience. CAASUWG input mechanism via the CAA user feedback area:

5. CAASUWG - Do what? CAASUWG has reviewed and processed a number of inputs. Part of this work involved definitions and requirements of the quick-look plotting by the CAA. This activity from the CAA is focused on facilitating a quick-look set of plots, based on CAA data, of various instrument data sets.

6. CAASUWG- Quick look plotting Basic idea is to have a database of pre- generated, pre-defined plots from which the user will be able to select various combination of plot types. Resolution of these plots is: 1,6,24 and orbit. The current working list of ‘plot subjects’ includes: ‣ FGM: B field magnitude, GSE ‣ EFW E field GSE, spacecraft potential ‣ WHISPER – Spectrogram (Active) Full range 2-80 KHz ‣ WHISPER – Spectrogram (Passive) Full range 2-80 KHz ‣ CIS and PEACE moments (density, temperatures) ‣ RAPID, CIS, PEACE Spectra

7. CAASUWG - Particle plots Will concentrate on CIS, PEACE (and RAPID) with query to teams. Requirement is to have quick look plots of: Omnidirectional / spin averaged spectrograms (already there for RAPID) Would be nice to have pitch angle (PA vs time not optimum because of energy dependences), 3 component: parallel, perpendicular and antiparallel, in same/similar units across instruments. Problems relate to which products to use in CAA database. The data is presented in different ways for each instruments. What product should be used to create the plot?

8. What product should be used? PEACE: Level 2 PAD distributions (MAR = most typical) PEA_CPPADMARH_DEFlux(2x12x32) AzimuthxPolarxEnergy change this to simple Energy versus time: average polar and azimuth? ~mean(*,*,0) Or just sum (*,*,0) (correct units?) NOT CAA PLOT! CAASUWG - Omnidirectional plot: What?

9. What product should be used? CIS: Level 3 distributions e.g. HIA_HS_MAG_IONS_PF = (8x16x31) PolarxAzimuthxEnergy change this to simple Energy versus time: average polar and azimuth? ~mean(*,*,0) Or just sum (*,*,0) (correct units?) Or just sosumAzimuth NOT CAA PLOT!

10. RAPID could be added onto CIS and PEACE plots (although units are small issue here) CAASUWG - Omnidirectional plot: What?

11. CAASUWG - PITCH ANGLES To avoid energy dependance of some distributions, have 3 panels Parallel AntiParallel Perp

12. CAASUWG - PITCH ANGLES RAPID IES to use same format? add levels to PEACE? (units, different ‘zone’ size)

13. CAASUWG - PITCH ANGLES How to do this: CIS = no PA data, requires FGM CAA product and rotation matrix need rotation matrix and preferred FGM data (value added product, spin res FGM) PEACE= PA data in file, but based on PEACE derived high res field, NOT CAA FGM. Should we use PAD or wait for SPINPAD. (PA based on PEACE dervied FGM product, not CAA) RAPID - Separate angle x angle matrix of pitch angle allocation, but based on IEL information. RAPID have been requested to look at rebinning high res CAA data.

14. CAASUWG - PITCH ANGLES How to do this: CIS = bin width 22.5 degrees ( around 0, 90 and 180 degrees) PEACE= bin width 15 degrees (around 0, 90 and 180 degrees) RAPID= bin width 20 degrees (around 0,90, 180 degrees) maybe
