Description The load_tdb() function loads a TDB (TES Data Base) file. It returns a structure containing one structure for each record in the file. By default however, Xaxis and Double records are not merged. If the distribute flag is set, the appropriate Xaxis records are copied into any Double records that have an xdata value set (and the xdata value is removed). If the reform flag is set, records of the same type are collated together. Any records that are of the same type, but which are not homogenous (ie: Double records both with and without an Xaxis set) are padded out to be homogenous, using empty strings.
Arguments and Return Values Input: filename of the tdb file Output: a structure of vectors arranged according to the options set
Usage Syntax: load_tdb(filename=STRING [,distribute=BOOL] [,reform=BOOL])
Examples filename is the input file and full path distribute is the flag to distribute the respective xaxis to each spectrum reform shapes all the matching data into a .Xaxis and .Double containing structure
