Cube Generator Todd Bradley January 8, 2014

Updates Found case sensitive issue if dd.channel eq 'fuv' then instrument = 'CASSINI_UVIS_FUV’ For some dd.channel gives FUV and for others dd.channel gives fuv Fix this by inserting “strlowcase” like so if strlowcase(dd.channel) eq 'fuv' then instrument = 'CASSINI_UVIS_FUV’

Cube Generator Tutorial Cube Generator Fundamentals Download cube generator Download NAIF SPICE package Download UVIS raw data files Download appropriate spice kernels Run cube generator

Download cube generator Cube generator is software that generates calibrated UVIS data and accompanying geometrical variables Located on the UVIS team site http://lasp.colorado.edu/cassini/team-site/tools_software/ contact Laura Bloom about account username and password Cube generator executable is hopefully on the way so entire cube generator software will not be required.

Download NAIF SPICE package SPICE is a space geometry information system that assists scientists in interpreting observations from space-base instruments. Toolkits are available for C, Fortran, IDL, and MATLAB. http://naif.jpl.nasa.gov/naif/toolkit.html

Download UVIS raw data files DAPS3 UVIS team page http://cassini.colorado.edu/DAPS3/ (Contact Laura Bloom for account username and password) PDS http://atmos.nmsu.edu/pdsd/archive/data/

Download appropriate spice kernels These are a collection of kernels to be used with SPICE routines that provide geometrical information at some specific time during an observation https://cassini.jpl.nasa.gov/io/spice/ (contact JPL for account username and password)

Run Cube Generator First must register the DLM DLM (Dynamically Linked Module) provides interface between environment and SPICE Cannot be called within another routine Example

Loading Spice Kernels Can load a single kernel or load a batch of kernels all at the same time If loading batch of kernels then create text file with path and names Make sure text file resides somewhere within the path to the spice kernels Only provide path for successive directories after where the text file resides Example

Loading data files Can create a data cube from a single data file or from a batch of data files If loading batch of data files then create text file with path and names Make sure text file resides somewhere within the path to the data files Only provide path for successive directories after where the text file resides Example
