Quote:To me it doesn't save the instrument parameters under Setup/Preferences. I'm using the latest Firefox browser.Don't know if it's a bug or a problem with my own configuration.
Used acronyms: NEML=Naked Eye Magnitude Limit, SQM=Sky Quality Meter, TML=Telescope Magnitude Limit, CO=Central Obstruction, delta_m=difference in magnitudes between double star components, RoT=Rule of Thumb, pD_mm=proposed D_mm for resolving a binary (ident with earlier used pA=proposed Aperture), D_mm=Diameter (of scope) in mm, UCAC4=USNO CCD Astrograph Catalog 4th edition

Quote:A side effect of the Double Stars Database development is I'm forced to check my data, including the WDS. I send email regularly to Brian Mason and he always kindly reply me. Last time I submitted 1600+ magnitude errors on multiple systems.
Quote:well, bad on them if they don't ask to have it supported via the .gov domain. after all, they control the data.
Quote:if what you're calling magnitude errors are discrepancies in the pairwise entries (e.g., AB gives A as 5.0, AC gives A as 5.3) then yes, there are many of those in WDS. unavoidable, since they are typically measures made by different observers, instruments and equipment at different epochs.
Quote:i have to do quite a lot of cleaning and cross checking when i prepare my spreadsheet version of WDS, which i do about once a year. i don't mind that, because cleaning is a form of editing (censoring, adjudicating, overwriting) and it's better to have the unedited data always at hand. however it creates unique challenges for a query tool.
Quote:thanks for the fix. the lists i examined (including my wm. herschel attributions) look great. i realize that you have a lot on your plate. but an FAQ that explains how to create custom lists would be very helpful.
