What is a DP ID and what is Orig Filename?
A DP ID is a unique identifier assigned to every data product created by ESO. This identifier is composed of the instrument acronym followed by the date and time of start of the exposure (e.g. FORS1.2005-03-29T09:37:42.829). The Orig Filename is a temporary name used only at the instrument control workstation at the telescope. These names are displayed at the quick-look console and therefore may be used by visiting astronomers. • When I use the wild-card on some queries (e.g. Filter: R*), the results take much longer to show up. Why? The speed of completion for a given database query may vary depending on the amount of data to be searched and whether or not the database server uses the indexes associated to it. Under some conditions (specially when using wild-cards), these indexes are ignored and the server scans the complete database. Since the ESO databases tend to be large, scan times of up to a minute can be expected. • How is the DIMM seeing measured? Dou you store the FWHM measur
