This package contains the basic control software for the Xenics XEVA near-infrared slit-viewing camera for NIHTS (Near-Infrared High-Throughput Spectrograph) on Lowell Observatory's Discovery Channel Telescope.

To compile the shared object file requires that Xcode and its command line tools be installed.

TK: update python install instructions, including: swig astropy

Install homebrew.

Install libusb and libusb-compat using homebrew:

brew install libusb
brew install libusb-compat

To download & install this package:

cd ~/   # assume we are doing in user's home dir
git clone https://github.com/henryroe/NIHTS-xcam.git
cd NIHTS-xcam/xenics
make
cd ..
python setup.py develop

You will likely also want to install an image viewer. I use ztv, which can be installed from pypi with:

pip install ztv

TK: update

In python (preferably ipython to give you niceties like tab completion), bring the camera up and run a sequence

from xenics import XenicsCamera
x = XenicsCamera()
x.set_gain(False)
x.go(0.2, 1, 100, save_every_Nth_to_currentfits=10)
# etc....  take more sequences, whatever
# then, to shutdown:
x.close_camera()
