It appears that the part which loads the data in `LoadISISNexus2` does not care about the order of blocks. The spectra in the blocks need to be contiguous though.\r\n2. The initial splitting up of the monitors works fine but for some (yet unkown) reasons insists in having the monitors at the beginning.\r\n3. 17787-17788 and 17789-17792 are not registered as monitors or detectors. My first hypothesis would be that this needs to be registered in the IDF\r\n--------------------\r\nFor further investigation:\r\n1. Is there a good reason for the monitors being at the front? (maybe with periods or monitor-only loading)\r\n------------------\r\nActions based on findings up to now:\r\n1. Remove requirement that monitors and detectors need to be in order\r\n2. Add an altered IDF\r\n\r\n"}}
