Description Converts Modified Julian Date to Julian Date
Arguments and Return Values Parameters: Numeric array specifying the Modified Julian Date Return Value: A double-format numeric array with the same organization as the inputs
Usage Syntax: MJD2JD(MJD) The Julian Date is a continuous count of days since noon UTC on January 1, 4713 BCE in the proleptic Julian calendar. The Modified Julian Date is a continuous count of days since midnight UTC at the beginning of November 17, 1858 (in the Gregorian calendar). An offset of 2400000.5 is the only difference between the two. This function just adds that offset. When MJD2JD() is entered without any arguments, it prints its description, as shown below.
