Hi, Please update your RHESSI software: A bunch of new software for the RHESSI quicklook data has been put online. There are a number of changes, the most important one is that the quicklook data is no longer appended to the level0 data files. Instead this data is accumulated in separate files, 1 for each day: files called hsi_obssumm_yyyymmdd_nnn.fits contain the "Observing Summary": count rates, modulation, ephemeris data, roll period, roll angle, pointing data, flare list and the quicklook summary page. Files called hsi_inslog_yyyymmdd_nnn.fits contain the "Instrument Log": total rates for each detector, monitor rates, and packet rates for the different knid of telemetry packets. For access to the quicklook data, use the HSI_OBS_SUMMARY object, see http://hesperia.gsfc.nasa.gov/ssw/hessi/doc/guides/obs_summ_access.htm. For the present, this will only affect data from 2002-09-18 on. Previous files with qlook data appended will still be used. Daily files will eventually be created for the whole mission though. Note also that this will not cause any change in the level0 files, so you do not need to download new versions of those files. If you are here at SSL, or at GSFC or ETH, with an automatically updated archive you should not notice any difference when you access the data (e.g., when you push the "plot observing summary data" button on the RHESSI GUI). If you are working without the updated archive, then the appropriate qlook data can be automatically downloaded in the same manner as level0 data, by setting the SKIP_NETWORK_SEARCH env varible to 0 in your setup.hessi_env file, or in the IDL session. These are small files, approximately 1.3 Mbytes per day, so this should not slow things down. This feature has not yet been tested, since the daily files have not been available, so let us know if there are problems. If there are problems, and you would like to download these files, they are found at: http://hesperia.gsfc.nasa.gov/hessidata/metadata/catalog In your setup.hessi_env file, define the env variable HSI_CATALOG_ARCHIVE to the directory that will contain the quicklook data. A preliminary whole-mission flare list will be online by Monday. It is not complete, the flare position is not yet available, and active region and GOES class have not been found for these flares. There are a number of false flares, due to background particles. Most of these have been weeded out, but it is a good idea to look at a GOES light curve if you are not sure about a given flare. There are also large gaps in the data, which will be filled in as needed. Most of the flares in the list are very small, but there are some large ones. An updated flare list document: http://sprg.ssl.berkeley.edu/~jimm/hessi/hsi_flare_list.html will hopefully be available next week too. (Note that all of these links are available via the Rhessidatacenter web site.) Also there are new Quicklook countrate plots; in addition to the current plots, e.g., http://hesperia.gsfc.nasa.gov/hessidata/metadata/2002/09/18/ hsi_20020918_175040_rate.png There are plots of "corrected" count rates, with the jumps due to attenuator state and rear segment decimation taken out, e.g., http://hesperia.gsfc.nasa.gov/hessidata/metadata/2002/09/18/ hsi_20020918_175040_corrected_rate.png. These are easier to look at. Plots for the mission before 2002-09-18 will be regenerated. The software is online, though. You can get a corrected count rate plot using the plot method for the hsi_obs_summ_rate object (see how to get this plot in the obs summary document referenced above) by setting the keyword /corrected in your call to the plot method. Try it out on some X flare with a bunch of attenuator state changes, it seems to work pretty well. Please do not use the corrected rates for any real science, they only exist to make clean plots without all of the ups and downs caused by instrument configurations. That's all i can think of for now, i'm sure that i'll be notified of any omissions or errors in the morning... jm
