Night sky line spectra were acquired during May 2012
engineering. Below we present the flux from the night sky as
measured by MOSFIRE. The first column of data is the flux
density in units of (ergs/s/cm^2/Hz/arcsec^2) while the second column
is the same data converted to ABmag/arcsec^2. The data are
stored in FITS format.
These lists were developed and graciously provided by
Dr. C. Steidel (mosfire team).

NOTES
The FITS files contain the flux density and AB mag of the sky
emission, respectively. The wavelength corresponding to the FITS data is
stored in the FITS header. Two keywords are necessary to
interpret the wavelength:
- CRVAL1 - the wavelength for the first pixel.
- CD1_1 or CDELT1 - the wavelength per pix scale.
The comments for both those keywords indicate that they refer to
the RA. Ignore the comment and assume these two keywords are
used to specify the wavelength. The plots above were
created using the CRVAL1 and CD1_1 (CDELT1) keywords.
