Dear Mr. Phillip,
Its been long time we haven't get in touch.Hope you still remember me. [img:f2b5c14464]http://us.i1.yimg.com/us.yimg.com/i/mesg/tsmileys2/04.gif[/img:f2b5c14464]
I have a few questions here:
1. Why there is a big different of the pixel value of fits image and rfits image?I have made comparison between them for certain pixel, the fits image gave ~1600 ADU but the rfits image gave only ~120 ADU.Does this will affects the result of measurement analysis especially the SN ratio?
2. Following on that problem, I have changed a parameter of the rfits task : I set the scale to no. I thought the pixel value will remains the same after the conversion of rfits but totally not, infact the value has changed to negative value to ~ -30,000ADU. Why is that so? I'm getting more confusing now.what are the parameter that need to be changed?
Please help me Mr. phillip. I have to submit this analysis report by end of this month.
Thank you.Hope to here from you ASAP.[img:f2b5c14464]http://us.i1.yimg.com/us.yimg.com/i/mesg/tsmileys2/04.gif[/img:f2b5c14464]
