Installation¶
To install, use the command line:
% pip install bossdata
To upgrade to the latest version:
% pip install bossdata --upgrade
Requirements¶
The following additional pacakges are used by bossdata and will be installed automatically by pip, if necessary:
- requests
- progressbar
- astropy
- fitsio
- numpy
- pydl
Numpy Performance Issue¶
Note that some operations run much slower (but still correctly) with numpy versions 1.10.0 and 1.10.1 so these should be avoided if possible. See here for details. To determine which version of numpy you are using:
import numpy
print numpy.version.version
The best solution is to use version 10.0.2 or later. If this is not possible, revert to numpy 1.9.3 and astropy 1.0.4. For example, with conda:
conda install numpy=1.9.3
conda install astropy=1.0.4
Optional Dependencies¶
The following packages are optional and enable additional functionality. They will not be automatically installed by pip, but will be used when available.
- matplotlib (used by the bossdata.plot module and bossplot script)
Quick Demonstration¶
If you have matplotlib installed, you can quickly test that everything is working with:
bossplot
This should download a small data file for a single spectrum and plot the data in a window. Close the plot window to exit. For more information on bossplot and other available command-line scripts, see Executable scripts.
