Raw files for education

Excuse me if this is the wrong forum to post this topic.

I will be teaching a course for young (high school age) students at Northwestern University in a program called "Center for Talent Development."  Basically, it is a program for extremely smart young students who are interested in summer enrichment activities. The class is called How to Image the Sky and I plan for each student to complete a small discrete variable star research project.  I was told that I would have approximately 8- 10 students enrolled in the class but today I found out that I will have 18.  The good news is that so many students want to take the class!  I have been collecting data (imaging) the last  year to collect enough data ( 8 variables) so that each student can work on a different variable (eclipsing binary) star.  

Here is my question.  Would anyone be interested in sharing raw images with me to fill out my program?  I need data for 8-10 more variables.  We will not upload any of the data or publish any of the data.  It is solely for students to practice plotting light curves.  I know I can request ASCII data on variables but the idea is for the students to work directly with raw image data. I was thinking that they could be shared via VPhot ?? unless there is a better way to share them.  Ideally, they are time series short-period variables.

Thank you for taking the time to read this post.

A few short period stars

I've got images for DY Peg (V), TZ Aur (BVRI), SZ Boo (BVRI), and BS CrB (BV) - let me know if any of those work and I can try to share them via VPhot (haven't tried that before so I'm not sure what exactly it shares) or I can set up a folder where you could access and download the images if that's easier.

The data is already in WebObs for these (observer code DMIA) if you wanted to check out what all is in the data sets.

Thank you!

Great, I'll take TZ Aur (B & V) SZ Boo (BV) and BS CrB.  However you want to share is fine with me - whatever is easier for you.

VPhot User ID

Walter (WGL):

Ready to share some images as discussed offline. However, your observer code has apparently not been registered in VPhot. Have you ever set up your VPhot account? Is so, what id did you use?

I suspect WGL is not your observer code since the first letter should probably come from your last name (G) not first (W)?

Target Images

Walter (GWL)

You should now have 15 sets of target images on your vphot account. Take a look.

Thank you

I just got done downloading all your data, I wanted to thank you one more time for your help!

I have the same request

I was hoping, almost exactly three years later, in a world we could not have imagined back then, to piggy-back on Walter's original request: I'm trying to find a few sequences of reduced/calibrated images my 2-yr college students can use to generate light curves.  Any help would be much appreciated.

Stay safe,

Shared Data for Light Curve Practice

I'm happy to share a recent time series of an HADS star (V417 Boo from 3-19-2020) in both B&V filters, if the 2-color aspect isn't overwhelming.  The color change makes for an interesting discussion.

 

EDIT:  Walter, I've tried both GWL and WGL, and both fall flat

These look great

I am brand new to AAVSO. Is the next step for you upload the images to my account? If so, my id is PRGA.

Thanks so much!

More images for light curve generation

Hi, Richard:

I've got image sequences I can offer you for an eclipsing binary (V1160 Cas) and for an exoplanet transit (HAT-P-54b). Interested? (I've got both primary eclipse and secondary eclipse sequences for V1160 Cas, which is kind of interesting since the two eclipses are very nearly identical.)

Absolutely!

Thanks very much

Curating and publishing a few

Curating and publishing a few images or image series as examples and tutorials might be a role that each of our Sections should take on.

These will be great data to use with my students.

Thanks again,

Data For Student Use

Glad these can help.  I tend to collect interesting time series data for student use so they can have something "cool" to process, without spending weeks and weeks waiting for an outburst.  Its a little like salting a sandbox with fossils and a few gemstones, but once they learn the techniques, we can turn them loose on all sorts of other targets.

 

Its amazing how easy VPhot makes photometry, but your plot looks like its coming from AstroImageJ, which is what we use with ourhigh school and college students so there's no price barrier to everyone having access.  Its also nice if everyone can work on their own local computer without having to share central resources via VPN or the like.

Clear skies,
