Definition of RJD/MJD/BJD

All times should be measured from the mid-point of exposure (or flux weighted time)

• MJD: Modified Julian Date : JD − 2400000.5

• RJD: Reduced Julian Date : JD − 2400000

• BJD: Barycentric correction of JD for the line of sight being considered

RJD = MJD+0.5

BJD - 2 400 000 = ~MJD+0.5 (to within ~8 minutes)

BJD = 2 400 000+0.5 + MJD

BJD - 2 400 000.5 = MJD (to within ~8 minutes)
