Following are a list of institutes and telescopes codes (are some of them adopted by the IAU?): KBOU Space Env. Lab, Boulder, Colorado KHMN Holloman AFB, New Mexico HTPR Haute-Provence LEAR Learmonth MEUD Meudon MITK Mitaka NOBE Nobeyama ONDR Ondrejov KANZ Kanzelhoehe Solar Observatory KSAC Sacramento Peak, New Mexico BBSO Big Bear Solar Observatory KPNO Kitt Peak National Observatory MEES Mees Solar Observatory MWNO Mt.

File extension name should be as informative as possible, indicating the data format of the file: CDF Common Data Format FTS FITS GIF GIF JPG JPEG MPG MPEG-1 (possibly MPEG-2 as well) PPM Portable pixmap YOH Yohkoh format In case a field is not determinable, that field should still be filled with proper number of the letter "x".
