Calculate S/N and exposure times for
stellar spectroscopy with the `ARC Echelle Spectrograph (ARCES)
`_ on the
`ARC 3.5 m Telescope `_ at
`Apache Point Observatory `_.

The ARC Echelle Spectroscopic (ARCES) Exposure Time Calculator, or ``arcesetc``,
is a simple exposure time calculator for the ARCES instrument on the
Astrophysical Research Consortium (ARC) 3.5 m Telescope at Apache Point
Observatory for stellar spectroscopy. Users can supply ``arcesetc`` functions
with the spectral type of their target star, the V band magnitude, and either:
the desired exposure time in order to determine the counts and signal-to-noise
ratio as a function of wavelength; or the desired signal-to-noise ratio at a
given wavelength to determine the required exposure time.

We estimate the count rates for stars as a function of wavelength by fitting
15th-order polynomials to each spectral order of real observations of a star of
each spectral type. These polynomial coefficients and some wavelength metadata
are stored in an HDF5 archive for compactness and easy of reconstruction. Then
upon calling ``arcesetc``, the archive is opened and the spectral order closest
to the wavelength of interest is reconstructed from the polynomial
coefficients, for a star of the closest available spectral type to the one
requested. 


Installation
------------

You can install ``arcesetc`` with pip::

    pip install arcesetc

You can install ``arcesetc`` from the source code by doing the following::

    git clone https://github.com/bmorris3/arcesetc.git
    cd arcesetc
    pip install .

``arcesetc`` requires python >=3.5, numpy, astropy, h5py, and matplotlib.
