Hessi Data Analysis Setup (at MSU)

1. Make setup.hessi_env on your home directory or copy it from ~sato/setup.hessi_env

2. Edit your data path of HSI_DATA_ARCHIVE in setup.hessi_env file
(HSI_DATA_ARCHIVE path must be your data directory)

3. Edit your .cshrc to include `setenv SSW_INSTR "hessi xray spex goes yohkoh sxt ucon" ' (we need hessi, xray and spex at least).

4. Download RHESSI data from http://hesperia.gsfc.nasa.gov/hessidata at GSFC.

GUI Interface
IDL>hessi <---That's it!

Commandline Interface (sample)
Plotting:
IDL>ol=hsi_lightcurve()
IDL>ol->set, filesname='hsi_20020421_011200_007.fits'
IDL>lc=ol->getdata(ltc_time_res=1.0,obs_time_interval=['2002/0421 01:12:00','2002/04/21 01:19:00'],ltc_energy_band=[12,25,40,100],time_range=[0,0]
IDL>ol->plotman

Imaging:
IDL>o=hsi_image()
IDL>o->set,filesname='hsi_20020421_011200_007.fits'
IDL>o->set,obs_time_interval=['2002/0421 01:12:00','2002/04/21 01:19:00']
IDL>o->set,energy_band=[12.0,25.0]
IDL>o->set,time_range=['2002/04/21 01:13:20','2002/04/21 01:13:40'] ;Imaging time
IDL>o->set,as_roll_solution='PMT',as_extension=[-500,500]
(If this process does not work, see Sam's Clean Tutorial to determine SPIN Period)
Full Sun Imaging:
IDL>o->set,image_algorithm='bproj'
IDL>o->set,image_dim=[128,128]
IDL>o->set,pixel_size=[16,16]
IDL>o->set,det_index_mask=[0,0,0,0,1,1,1,1,1]
IDL>o->set,xyoffset=[0.0,0.0]
IDL>image=o->getdata()
IDL>o->plotman
Partial Sun Imaging:
IDL>o->set,image_algorithm='mem'
IDL>o->set,image_dim=[64,64]
IDL>o->set,pixel_size=[1.0,1.0]
IDL>o->set,det_index_mask=[0,0,0,1,1,1,1,1,1] ; No valid from GD1 to GD3
IDL>o->set,xyoffset=[**,**] <--- Input from Full SUN Image
IDL>o->set,sato_chi_limit=1.0
IDL>image=o->getdata()
IDL>o->plotman
