Files and Data
------------------------------------------------------------------------
There are two tar'd files available for download: 
    o Ostlin2009_lya.tar.gz
    o Ostlin2009_ha.tar.gz

Respectively, these contain the images of the six galaxies in Ly-alpha
and H-alpha. For each galaxy in each emission line, two images are 
distributed: the (continuum-subtracted) line image, labeled _lya.fits 
and _ha.fits ; and the (line-subtracted) continuum image image, labeled
_lyac.fits or _hac.fits. All images are calibrated in [erg/s/cm2/AA], so
to go to line fluxes, you need to multiply by the bandwidth. 

No H-alpha image is available for Tololo 65. Furthermore, the ACS/SBC
imaging for Tololo 65 suffered a guiding failure and data for this
galaxy are on the whole rather poor.
