I am talking about the very small grains in the interstellar medium.

I recently came across a paper where there was a term ''stochastic heating of very small grains". I went through some papers on this area but I am still confused about it. What is the vibrational temperature associated with very small grains? Does temperature has got a meaning if it's a highly...

So are you saying that the photograph will be still 2 dimensional? I am considering time as a dimension not a parameter.

If time is a dimension, what would be the dimension of a photograph in such a space?

Sorry...that's what I meant. The resolution is cut by half for 60''/sec scan speed. Can you please explain why it's so?

I came to know that the PACS instrument of HERSHEL has a resolution of 5" at a scan speed of 20''/sec whereas it's 10'' at 60''/sec. The resolution has almost doubled with the scan speed. Can you please tell me why it's so?

I have been working with some Herschel images and I am finding it difficult to extract the astronomical sources from the image. The image background is extremely non uniform so i am not able to differentiate between the background and the source. I used some tasks in HIPE like source extractor...
