General
Some tools of the
NRH software
have been adapted to run on HESSI data.
This software is available from the NRH tree of Solar Soft
To use:
1 - load the nrh software from Solar Soft
2 - Run SSWIDL
Enter HESSI_NRH
This procedure is a GUI to access all the facilities
Image analysis (Tv, Contours, Profile, Pixels coordinates, ...)
Display many images in the same window
Movie from images in the FITS file
Source Tracking (spatial and temporal evolution of different emitting components)
Superposition of data from various instruments and results of Sources tracking
or pixels coordonates
Projection of images on one direction and time evolution
For more information see the
NRH software
Simulation
This software can be tested with simulated HESSI images written in
NRH file format
For this:
1 - Make HESSI fits image files using
HESSI software
, or NRH_HSI_IMAGE (from the NRH software). The NRH_HSI_IMAGE procedure
generates a serie of HESSI fits files with two flares and a motion betewen
succesives images (method Back Projection or Clean.)
2 - Convert these files in a NRH fits file, running NRH_HSI_FITS (from the
NRH software).
3 - Run HESSI_NRH (the GUI interface) to analyse the serie of images in
NRH format file
Example:
NRH_HSI_IMAGE ;to create simulated images
by Back Projection method, or /CLEAN
List = FINDFILE('hsi*is.fts') ;get the list of the
files created
NRH_HSI_FITS
; convert in a multi_images file
HESSI_NRH
;to have the widget interface
for images analyze
File format
A complete description of file formats is given on the document about
NRH file format
File name
for HESSI is
