Remarks:
Data from the OGLE II Galactic Disc Photometric Database (Szymanski 2005, Udalski et al. 1997) for Mira in Centaurus and Norma were used to present 32 such variables in Greaves (2008).

In this note a further 46 Mira variables from the OGLE II Galactic Disc data for the remaining fields in Scorpius are presented.

Again, the one thousand day duration of the survey, the magnitude range of the experiment, the seasonality of observation relative to typical period length (especially so in this instance with Scorpius being a Zodiacal constellation), can lead to only approximate periods being given at times, or with sometimes only minima being available for epoch determination (appropriately noted in the above table), if any note of epoch can be made at all. Further, although the periods and general shapes of the lightcurves are typical of Miras, full amplitude is somewhat suppressed at times as the survey used a passband near to Cousins I, rather than the normally expected Johnson V, and I band magnitudes are not prone to continuum absorption by titanium oxide and/or vanadium oxide which can represent a substantial part of the amplitude for Miras in Johnson V and the visual.

None of the stars are noted in the GCVS, NSV (http://www.sai.msu.su/groups/cluster/gcvs/gcvs/iii/html/ ) nor ASAS variable star listings (http://www.astrouw.edu.pl/asas/?page=download ), the resources most likely to cover these regions, which is to be somewhat expected as Mira variables will on the whole have V-Ic colours of 2, 3 or higher, thus often being much fainter in the more traditionally used Johnson V and visual ranges used in surveys.
