you should see a directory

Vivienne_Spectra/

which takes you to a data disk so that in future we can move large files about.

At the moment there is a modestly sized tar file with

1580 spectra of the 2200-3000A region for SDSS DR7 spectra with an
MgII absorber in the restframe wavelength interval 2740-2830A. Should
provide good statistics to understand where the reconstructions are
falling over as a function of absorber EW and delta_v [relative to
systemic].

There is also an ascii file with the six-components for fitting

mgii_6c_150814_v2.comp

and the associated wavelength array

wav22003000.dat

Think the old component file should be OK but if something doesn't
look right just say. Would mean my spectrum shape-morphing has
changed, in which case I can rederive a set of components using the
current implementation.

unzip the mgii_dr7_040110_170627.zip file

and find a directory mgii_dr7_040110_170627/
created and also a
__MACOSX/
directory which can be deleted

the  mgii_dr7_040110_170627/ directory
contains the original four-band spectra supplied to Viv - flux, noise,
mask, flux_morph

in

mgii_dr7_040110_170627/contfit_dr7

there are the 27507 files from Viv's continuum-fitting and
27507 companion files e.g. spSpec-51578-0296-356_info.txt
with the component fitting information
