There are two categories of search methods for the Herschel II observing program, "Manual" and "Device-Aided." To be considered for the "Manual" certificate, 100% of the objects have to be obtained in this manner. A space is provided on the submittal form to indicate your search method. Definitions are:

Manual: This term is hard to describe in words that will cover all contingencies that technology may potentially bring. In general, observers know the intent of the word "manual" and should use their judgement accordingly. There are two components to "manual." One is that the observer hand-guides the telescope to the object. The other is that the observer uses his/her eye to see through the telescope to navigate to the object. Navigational aids such as Telrads® or computer-generated charts fall into this category. On observations submitted indicating that 100% of the objects have been searched using the manual method, there will be an "M" designation on the certificate next to the certificate number.

Device-Aided: The observer uses aids such as manual or digital setting circles, computer devices, screen locating, or other aids that guide the telescope to the object. There will be a "DA" designation on the certificate next to the certificate number.
