public static short CioArray(
	double JdTdb,
	int NPts,
	ref ArrayList Cio
)

Public Shared Function CioArray ( 
	JdTdb As Double,
	NPts As Integer,
	ByRef Cio As ArrayList
) As Short

Parameters

JdTdb  Double

TDB Julian date.

NPts  Int32

Number of Julian dates and right ascension values requested (not less than 2 or more than 20).

Cio  ArrayList

An arraylist of RaOfCIO structures containing a time series of the right ascension of the Celestial Intermediate Origin (CIO) with respect to the GCRS.

Return Value

            0 ... everything OK
            1 ... error opening the 'cio_ra.bin' file
            2 ... 'JdTdb' not in the range of the CIO file; 
            3 ... 'NPts' out of range
            4 ... unable to allocate memory for the internal 't' array; 
            5 ... unable to allocate memory for the internal 'RA' array; 
            6 ... 'JdTdb' is too close to either end of the CIO file; unable to put 'NPts' data points into the output object.
            

Given an input TDB Julian date and the number of data points desired, this function returns a set of Julian dates and corresponding values of the GCRS right ascension of the celestial intermediate origin (CIO). The range of dates is centered (at least approximately) on the requested date. The function obtains the data from an external data file.
