Quicklook Exercises

First, you need access to the data files by either:

1.  Copying the files from the CD that will be available during the workshop to your computer (put in your IDL working directory, HSI_DATA_ARCHIVE, or HSI_DATA_USER), or

2.  Using  the data archive at SSL through the automatic search_network feature by typing (in your SSW IDL session):

hsi_server, /ssl

Notice when you're done that the files needed were copied to your HSI_DATA_USER directory (or if you didn't define HSI_DATA_USER, then your temp directory.  To see what your temp directory is, type print,get_temp_dir() in SSW IDL)

Using the RHESSI GUI:

1.  Make an observing summary count rate plot for the flare on February 20, 2002 with the highest total counts less than 1.e6, and position greater than 600 arcsec  from the center of the Sun.

2.  Make a lightcurve (from raw data, not observing summary qlook file) for the same flare  with a time resolution of 1 second and the four energy bands 3-6, 6-12, 12-25, 25-50 keV.

From the CLI:

1.  Get an array of the start and end times of SAA on February 20, 2002.

2.  Using hsi_flarecat, retrieve a list of flare numbers that have a peak rate between 1000 and 2000 counts/sec, were in attenuator state A1 at the peak of the flare, and were in attenuator state A3 during part of the flare.
