We investigate the X-ray and optical properties of a sample of X-ray bright sources from the Small Magellanic Cloud ( SMC ) Wing Survey .
We have detected two new pulsars with pulse periods of 65.8 s ( CXOU J010712.6-723533 ) and 700 s ( CXOU J010206.6-714115 ) , and present observations of two previously known pulsars RX J0057.3-7325 ( SXP101 ) and SAX J0103.2-7209 ( SXP348 ) .
Our analysis has led to three new optical identifications for the detected pulsars .
We find long-term optical periods for two of the pulsars , CXOU J010206.6-714115 and SXP101 , of 267 and 21.9 d , respectively .
Spectral analysis of a sub-set of the sample shows that the pulsars have harder spectra than the other sources detected .
By employing a quantile-based colour-colour analysis we are able to separate the detected pulsars from the rest of the sample .
Using archival catalogues we have been able to identify counterparts for the majority of the sources in our sample .
Combining this with our results from the temporal analysis of the Chandra data and archival optical data , the X-ray spectral analysis , and by determining the X-ray to optical flux ratios we present preliminary classifications for the sources .
In addition to the four detected pulsars , our sample includes two candidate foreground stars , 12 probable active galactic nuclei , and five unclassified sources .
