Design and Development of Observation Log Tool for Lijiang 2.4-meter Telescope

The observation log of the telescope is very useful for the observers on data processing; it is also very useful for the observatory on data storage, archiving and publication. Observation log can provide all kinds of information of the observation for the observers to judge the quality of the observation data. During the observation, the observation log is always recorded by the observation assistant or the observer himself manually. On one hand, the information in the log might not be specific enough, sometimes might have mistaken in writing. On the other hand, the papery observation log is also inconvenient for the data archiving and publication. Based on the observation data of YFOSC, we designed and developed an observation log tool to record the observation log automatically. This tool can record the observation log automatically by reading the fits header of the observation data. The users can also revise the errors they found in the records of the observation log. The observation log is also related to the observation time application system by using the unique proposal ID to manage the observation data, thus can package the observation data for the specified observer. In summary, by using the observation log tool, the observation data authority can be protected by the system during the data protection period; the influence of mistaken writing can be avoided; the accuracy of the observation log can be increased and the observation efficiency can be improved.
