HI,

I have a couple questions about VPhot

1) I Have a DSL internet connection with 1 Mbps upload speed but when I upload images in VPhot I only see a maximum upload speed of 104 kbps in the upload image box. Is VPhot server the bottleneck?

2) I changed my transformation coefficients in the Telescope Information by manually entering them.

    But VPhot says " Transformation coefficients:    Load values from INI file " What is a INI File?

3) I get a message in red about registering my telescope when I try to upload images (see attached .gif

      file) . However I am able to upload files. Is this due to not entering my Trans coeff with a INI file?

Thanks

Erik

There is no programmatically coded speed limit to the Amazon Web Service VPhot servers. Of course, there is some maximum transfer speed limit to their network cards? Quite high, I'm sure? On my FIOS connection, I can upload at 2 MBps from one computer but only 500 KBps from the other. So, one of my network cards is quite slow! There are also intermediate web providers between you and AWS that will impact your speed. I know for a fact, that they can negatively impact your speed to AWS.

2) I changed my transformation coefficients in the Telescope Information by manually entering them.

    But VPhot says " Transformation coefficients:    Load values from INI file " What is a INI File?

An ini file is a summary file generated by Transform Generator and Transform Applier that includes your transform coeffs and errors. In the recently installed update to VPhot (4.0.4), an ini file can be imported directly into your telescope setting page rather than manual entry, which still works. (Note, this feature has a bug at the moment that is almost resolved by new coding).

3) I get a message in red about registering my telescope when I try to upload images (see attached .gif

      file) . However I am able to upload files. Is this due to not entering my Trans coeff with a INI file?

The error message in red indicates that VPhot doesn't think you have selected a registered telescope setup in VPhot. I get the impression that you did? I assume when you created the telescope setup in VPhot that you saved the page? You would need "some" telescope name selected in order to upload so I'm confused by your comments. Could you be a little more explicit about what you were able to upload and whether they ever got to your image list?

Hi Ken,

Thanks for your answers.

Question 3)  I set up my telescope registration name back in 2018 (RC10 0.67)

I manually entered new BVI transformation coefficients on 11/7/19 into RC10 0.67 telescope file

Now when I go to Telescopes my RC10 0.67 is greyed out, I get the red message when I attempt to Quick Upload .fit files but I click on RC10 0.67 anyways and they upload okay and all appear in my Image List

Common Scope

Erik:

IF your telescope is grayed out, I think you inadvertently checked the common telescope box. Log in and uncheck it. Report what happens? We may need to have George S log in to the database to fix this.

Ken

As an administrator, I unchecked it. Tell me what it looks like now?

Recreate Scope

Erik:

Interesting, although this does make sense to me.

The scope is still on my admin screen BUT since it was shown as a common scope, when I unchecked that box, VPhot did not know who it belonged to. IOW, it had never been registered to you personally.

So you need to recreate the scope in your account. Make sure that the common box is NOT selected and then save it. You should see it then.

I have taken a screen shot of the settings and will email that to you, in case you forget what some of them were.

HTH, Ken
