Re: [MaxImDL] Real-Time Photometry Script?

Hi all:

I'm wondering if anyone has written what we call a "Real Time

Photometry Script" for MaxIm. What we want to do is have the ability

to do some quick-and-dirty online photometry while observing. The

script would measure two stars (variable and comparison) and the sky,

subtract the sky from each, and then calculate the ratio of the

brightnesses, V/C. This isn't for science, but just to see if a star

is indeed going into eclipse. We observe a lot of variables for which

the elements are decades old, so predicted times of minima are often

off by quite a bit. The script should at least output a number with

the V/C and raw numbers to a text window. Logging the numbers to a

file would also be nice.



Has anyone developed a script that does this or something similar to

each image right after the image is taken?



Thanks in advance,

Cheers,

--Lee

Hi Lee,



I have just finished a quite long observing run where I faced the same

situation. But I found it very convenient to open the last few dozen

images and run the analyze/photometry with a var object and one ref

star, this goes quite fast, and one can add images as they come in and

produce the light curve on the fly. This is of course not as versatile

as a script, I agree.
