ommergelists (ommergelists-1.2) [xmmsas_20211130_0941-20.0.0]

The algorithm for sorting a SRCLIST table into increasing Right Ascension order is designed to work with a table with any number of columns that contains either RA_CORR, DEC_CORR or RA, DEC columns, with the former taking precedence. The algorithm works as follows-

- Produce an index list of the sorted Right Ascensions positions that gives the row number that each source in the table should be placed to be in the correct order.
- Double the number of rows in the table.
- Copy the original rows of the table to a position starting at the the last row in the original table plus one.
- Loop through the number of rows in the original table and replace each one by the appropriate sorted row from the appended rows using the index list.
- Delete the appended rows from the table.
