Hessi Catalog:

bullet Observing Summary: (Implemented)
bullet spin-averaged count rates in 9 energy bands, summed over detectors
bullet particle detector rates
bullet modulation variance, 2 Coarsest collimators
bullet S/C position
bullet Instrument Log: (Partially Implemented) Housekeeping, State of Health data for systems
bullet Flare List: (Implemented)
bullet Id number
bullet Start, peak and end times, in energy range [3.0, 20.0] keV
bullet peak count rate
bullet total counts
bullet Highest energy of observed photons
bullet Flare position, arcsec from Sun center
bullet Flags for flares that start/end in Eclipse or SAA
bullet Spectral catalog: (Not Implemented)
bullet count and photon spectra as a function of time
bullet Thermal + double power law photon spectra,
bullet dE = E/2 energy resolution.
bullet Image catalog: (Partially Implemented)
bullet Images in the energy bands given by the Observing Summary, If possible, Cadence determined by Count Rate. (Presently only 4 second peak)

Hessi Soc Tests:

bullet Local Tests: vc1 & vc3 simulated in raw data files, (no headers or frames). Realistic orbit data, HSI_CONTACT2FITS run from IDL session by JMM. Results in simulated data files online at http://hessi.ssl.berkeley.edu/data/test_data/.
bullet Test of SOC scripts: vc1 & vc3, simulated data, passed into ITOS, HSI_CONTACT2FITS run in script by TEQ, script then queues the data for CD production and FTP.
bullet End-to-End test: vc1 & vc3 from HESSI, no orbit data, no "flare", FITS file with Obs summary, but no flare list.
