Announcement: New Applications
We are excited to announce the launch of our new applications! We're opening up early access to our new applications for searching, downloading, and submitting photometric observations. You can now access these applications through these links:
We ask for your feedback in order to help us improve these applications. Please send feedback for the applications above to feedback@aavso.org. Note: please avoid duplicating submissions across the two submit applications.
Based on some assumptions about what you did, the following are my conclusions.
1. When you used Upload Wizard you entered extra requested information that was not available within your image's fits headers. As a result of adding that info, VPhot was able to calculate airmass.
2. When you used Quick Upload, VPhot observed that those necessary fits headers that you entered in Upload Wizard were, in fact, not present in the fits headers, and therefore VPhot could not calculate airmass and reported 0 (unknown/missing).
You need to use imaging software that includes those headers when an image is taken or you need to use separate software (e.g., F4W2HDU) to add such headers to the image before you upload them with Quick Upload.

HTH. If not, we should talk off-line?
