Q:
How do I find available redshift-independent distance estimates to NGC 1365?
A:
In the Simple Search screen, enter the object name "NGC 1365" and click Go (or enter key on your keyboard). The section of the query response labeled "Redshift-Independent Distances" provides summary statistics computed from the NED holdings, and includes a link to drill down for all available individual measurements.
Q:
How do I generate a spectral energy distribution (SED) of Arp 220?
A:
In the Simple Search screen, enter the object name "Arp 220" and click Go (or enter key on your keyboard). The section of the query response labeled "Photometric Data Points & SED" provides a tabulation of available individual measurements and related metadata in the NED holdings, as well as a plot of the SED.
Q:
How do I generate a table of basic information for all objects in NED with an available redshift within 1 degree of the north Galactic pole?
A:
Use the main menu and select Search Objects > By Parameters. In this screen, click on Sky Area Constraints, set System to "Galactic", and set GLat Range to "Between". Then enter 89.0d for Latitude 1 and 90.0d for Latitude 2. Click on Redshift Constraints and select Range Types: Available. Then scroll down to the bottom of the form, enter an answer to the question (intended to prevent bots from overloading the system), and click Go. Your request will be assigned a ticket number. This number is used to check the status of the query either by clicking on that value in the status region on the bottom of this page, or by coming back later (within 24 hours) and entering your ticket number into the Simple Search box on the NED interface. In either case, when the status reads "complete", you can download the results to your computer for analysis. Other samples of objects can be constructed in a similar manner.
