MRC B2158-206
-------------

Two candidate emission line galaxies were identified in the field of MRC B2158-206. Details are given in Table \[tab:elgresults\], and their locations are shown in Fig. 3(b). Thumbnail images of the candidate galaxies from each field, together with the measured fluxes, are shown in Fig. \[fig:2158objects\].

BR B0019-1522
-------------

Seventeen candidate emission line galaxies were identified in the field of BR B0019-1522. Details are given in Table \[tab:elgresults\], and their locations are shown in Fig. 3(c). Thumbnail images of the candidate galaxies from each field, together with the measured fluxes, are shown in Fig. \[fig:0019objects\].

Contaminants
------------

This section briefly addresses the likelihood that our method might incorrectly identify another sort of object as an ELG.

### Continuum objects

As per Figs. \[fig:trans\] and \[fig:simresults\], the sensitivity of our instrument varies from image to image. Therefore, it is possible that a flat-spectrum continuum object may be detected in some images but not others, thereby appearing to be a potential ELG.

We use the results of Section \[sec:sim\]
