I found the following info for t5577 in another thread.
T55x7 registers 32-bit data value
0x00107060 Block 0
0x1D555955 Block 1
0x5569A569 Block 2
0x5A956599 Block 3
Then I used proxmark3 to program these blocks of a t5577 tag. After that, I ran the following command to see how proxmark3 will interpret it.

Checking for known tags:
HID Prox TAG ID: 2006c6384a (7205) - Format Len: 26bit - FC: 99 - Card: 7205
Valid HID Prox ID Found!
______________________________________________
Here is my question. What is the relationship between the information extracted (HID Prox TAG ID: 2006c6384a (7205) - Format Len: 26bit - FC: 99 - Card: 7205) and those three blocks of UID data programmed into the tag in the beginning?
If I have the card number and facility code, how can I obtain those three blocks of hex data? How is this related to H10301 or 26-bit format?
Thanks,

The example you have given is H10301 / 26-bit.
You should search the forums.

To understand the H10301 / HID 26-bit or Wiegand 26 bit version you will find many questions/answers and links in the forum, about 13 pages on this Proxmark forum and more when you goolge, they will eventual lead you back to the two main support threads
T55x7 and Tags Emulation http://www.proxmark.org/forum/viewtopic.php?id=1767
and here
Wiegand card data formats http://www.proxmark.org/forum/viewtopic.php?id=1653
Like you, I have been inspired by crossing some HID questions (paticularly by my friend A. Patel) on the forum, I have searched and read all the 13 pages and more, from forum search in other keys words wiegand, H10301 Indala AWID etc, and was still very confused, until I did hand-mapping and learnt by mistake.
You will see contributors giving very vague answers, refusing to directly give you links or hints on certain files, informations ... I been through it At first I did resent Iceman, Asper, 0xFFFF, Marshmellow, but then by the end I understood them, this is an interesting sectors (historically and also technically said) and if I had the excel tool or someone did for me the mapping or giving me a tool to create data for emulation I would never understand this stuff. So I have to thank them afterwards not to take the fun away.
I am creating tools for this sectors. They are not yet completed, but already I am intrigued how people see and also should I trust them to one of the FORUM contributors to decide who can see them or release them freely.
I do understand the reason not to give mapping tool in the hand of beginner, to force them to learn the theory first. But if we believe in the mankind honesty, the tools, accompanying at the right time can encourage and support the student to learn his knowledge in this sector, too.
Direct answer to your question:
Yes there is a very clear linking of those information and the datas using by PM3 as you see here.

and yes there are tools available (That is one completed of many sectors of the mapping tool)

Thank you guys very much. Especially, more thanks to ntk for spending lots of time and providing very detailed instruction.

The screenshots of the tool you are creating look great. I hope you release it!

I will and I want crispy. It is only an excel sheet. What it can do you also can do too, using paper and a calculator. There is no mystery.
It only does quicker.So when you set out to test what you have learnt about HID in the theory, it would surely accompany you all the way, so you can use it to compare to check your conversion, you mapping your coding whether it is right or if incorrect you can see immediately where you make mistake for example.
But I do understand concerning of other forum uses, I do hope people will be honest and learn the basic theory first, because like addition in math and this tool is only like a calculator, if people misuse a calculator and rely too much on it, assuming one day battery run out they would not be able to do the simplest addition in mind or on their fingers... and that, is very bad.
