Descriptor LHCUTS

Another important descriptor is the real descriptor LHCUTS (6 values). It contains the user specified low + high cuts (which are e.g. used in a LOAD/IMAGE command) in element 1 + 2 and the physical minimum and maximum of the data frame in element 3 + 4 (the elements 5 + 6 are used in some special applications only). When you enter your data frames into the system via INTAPE, the descriptor values LHCUTS(3,4) are set up correctly. When you write your own conversion program make sure to fill LHCUTS correctly. All MIDAS core commands operating on frame data update LHCUTS(3,4) accordingly. The MIDAS commands STATISTICS/IMAGE or FIND/MINMAX will also store the right values into descriptor LHCUTS.
