/* Introduction */
'''IMPORTANT NOTES ABOUT THE NEW SOFTWARE'''
* '''THE NEW SOFTWARE HAS DIFFERENT FILE NAMES AND HEADER KEYWORDS THAN PREVIOUS DATA.''' If you use this information in your analyses, you will have to update it. The filename format has been standardized to <Instrument>_YYYYMMDD.####.fits, where the instrument is SHA, SHD, or SHH to designate which SHOC box is being used. Please check the header for of a new data file or the wiki [http://topswiki.saao.ac.za/index.php/SHOC#FITS_Header_Keywords FITS header keywords ] (the "new" keywords are directly from the Andor iXon camera under Linux).
* '''THE FILE SIZE IS NO LONGER LIMITED TO 2 GB. ''' This means that if you take large data cubes, the file size has ''no limit'' (this is because we are no longer on a Window-based, 32-bit, operating system). If you end up with a very large file, data analysis can be difficult. We are working on an efficient method to automatically split files into smaller sizes, but for now users need to be aware that requesting a large number of images in one file could return a very large file size (and if you mistakenly delete your file, you have lost alot of work!). It is recommended that multiple files be manually taken. ''If you have any questions or problems with the data, feel free to contact carel@ saao.ac.za or amanda@ saao.ac.za.''
* '''If you use the GPS, please set the pulse width to 10 microsec.''' It is currently defaulting to 1 microsec, and this will be fixed in the next version of the software.
