  1. OSPEX – Object Spectral Executive • OSPEX – new, but completely separate, object-oriented version of SPEX • Documentation: • Complete OSPEX Explanation • List of OSPEX Control/Info Parameters • OSPEX First Steps • Run OSPEX via • GUI • CLI • Combination of GUI and CLI • Batch script files • Start OSPEX via • o = ospex() or ospex_proc,o Default is to start with GUI • o = ospex(/no_gui) or ospex_proc,o, /no_gui

  2. OSPEX Input Options • RHESSI Spectrum FITS File • Use spectrum object through GUI or CLI • Select finer time bins here for flexibility later • Include some background • Write output FITS file and associated SRM file • Set input file for OSPEX to spectrum FITS file • Set input SRM file for OSPEX to SRM FITS file • RHESSI Image Cube FITS File • Use image object through GUI or CLI • (hsi_multi_image object for now, hsi_image object soon) • Select multiple time bins and/or multiple energy bins • Write output FITS file • Set input file for OSPEX to image cube FITS file • You will be prompted to define the region to create spectrum from • User Data • Use set method from CLI to set spectrum data, errors, etc. See OSPEX Doc for details

  3. OSPEX Steps • Select input data • Select background time intervals • Select fit time intervals • Select fit function and starting parameters • Select energy range to fit • Select looping options • Do fits • Review fit results • Write script to store your parameter settings • Save fit results

  4. OSPEX GUI • Starts by default but if you close it, type o -> gui • Any of OSPEX sub-widgets can be used without using the main GUI • OSPEX CLI • OSPEX object design is identical to RHESSI objects • OSPEX object is chain of objects, with an object for each type of data • Uses SET, GET, GETDATA, PLOT, PLOTMAN methods • To retrieve data from any object in the chain, use the class_name keyword • Examples: • To retrieve the raw data, use data = o -> getdata (class=‘spex_data’) • To retrieve the background data, use bk = o -> getdata(class=‘spex_bk’) • EXCEPT: No getdata from top level, ,i.e. d = o ->getdata() not allowed. This will be changed.
