Since spitzer and Hubble data is available to you in an unprocessed form, you should be able to compare and contrast with their processed data and try different things till your numbers line up (assuming they don’t do anything too sophisticated, but at least it will tell you how close you are) | |
| Jan 10, 2023 at 21:51 | comment | added | lol | Thank you very much for your comments. @JustinT, I tried, but there is a difference that I need to know if I can ignore; probably not. On the other hand, I suppose it is hard to find a paper describing that conversion: my idea is that the conversion is assumed as "general knowledge," which is not worth mentioning. However, thanks for the idea, I will try papers describing catalogs, which should give more technical details. | |
