Changes Since Last Version

PDS, DIF, PLT and HKL files can now be read. All the spectra in a file are read. Further information in the help on the File Reading Window.
background subtraction operations can be performed. Further information in the Background Subtraction Operation Window help. ( select 'Background Subtraction from the operations menu ).
a spectrum may be generated by collecting cursor positions from an existing plot. Further information in the Collect Points Window help. ( Select 'Collect Points' from the Modes menu).
many minor bugs have been fixed

MOTPLOT ( and all other motif 1.2 based programs ) cause the Sun X server xnews to crash. This is fixed in OpenWindows 3.3 which comes with Solaris 2.3. If you are not able to upgrade to Solaris 2.3 then you should try to use the MIT X server Xsun.
On some Pericom X terminals MOTPLOT only works the first time you login after a reboot. This mysterious problem seems to be in some way connected with font allocation but has not yet been completely tied down.
On some Pericom X terminals MOTPLOT causes everything to stop after a while. This appears to be caused by running out of memory. It can usually be fixed by changing the X parameters of the terminal so that Backing Store and Saves Under are switched off.
On some Silicon Graphics displays the colours used by MOTPLOT are lacking in contrast. In a future release colours will be under user control
