SharpCap Forums

I've used the ADV format for maybe 20 occultation observations and it all seems to work fine. The smaller file sizes are a really nice benefit.

I haven't had any feedback from others at IOTA about the changes to ADV format.

A long series of flashes is impractical. Recordings are usually 2-3 mins long and the event time uncertainty can be tens of seconds so need to leave a 1.5 -2 min clear window. Also can't afford to be running around too much as it gets hard to coordinate. The flasher might also be handheld so could m...

For ADV format the various software used for processing the light curves would need to be updated to use the information. I think it would be a per file basis as I don't think there is a reliable way to associate a flash with an individual frame since the PC clock will not be accurate to UTC and pol...

Robin, is there a place in the ADV format that could store the timestamps from the IOTA-GFT? Or failing that add it to the camera settings file? It would be great if it was all stored in one place directly from SharpCap. Flux measurements across frames enable a calculation of how long the duration o...

Before you deploy any changes to ADV would you please consult IOTA. I can inform the current group dealing with the timestamp issues about the proposed changes.

I could be a tester.

The timestamp changes and bug have been reported to IOTA and onto the various IOTA groups with guidance of how to find errors in previous observations and how to use the right SharpCap version. Groups are in Europe/Asia/US/Australia so it is worldwide. At this stage we don't know how many observatio...

If you want to change the format for GPS cameras then please consult the ADV working group. Any changes you make might affect processing and could cause major problems. Perhaps use the accuracy field in the ADV file and put in a large dummy value to indicate it is not GPS. So perhaps set the clock f...

Thanks. Do not change anything for ADV recording of GPS cameras! Hristo can be contacted by email hristo_dpavlov@yahoo.com but may be slow to respond. Otherwise info@occultations.org to find someone in the occultation community. Mark Simpson has developed the Astrid camera/control module for occulta...

The change in the on screen time stamps for START TIME. Is this done for all formats and both video and still? Has this been changed for FITS?

After some more digging I did find a mention in the release notes on Aug 2023. The wording could perhaps be more explicit. I didn't spot it at the time.
