	Collections of text files gathered under each pa. 
10
	They were mems to myself over pa's lifetime. A lot of them were about a bug fixed. Nearly for every pa folder there is a file named "DB-table" that show what and how database tables were created and how data were populated
11
through using isql tools.  They may help one to understand programs but they are very raw and unorganized. They may describe an algorethm that is not current working version or contain some paramters that is not updated or a table since been modified.
12

    
13
	Some use examples:
14

    
15
	1. PA1665_i2
16

    
17
	a) How a ramp is programed into the MECAR:
18
algo-ramp, map-BruceMagnetPars.
19
	b) How chromaticity is seperated into P and dp/p dependent terms and then programed into "g' and 'h' tables of C453 cards:
20
see algo-chroms.
21

    
22
	2. Pa1666_i50
23

    
24
	Went along with the Main-Ring tradition the trims' strength are defined through scale factors that one raw unit produce 1 micron-radians beam deflection for 10 GeV beams, which Changes with the trim specification..
25
see uRadCalc.
26

    
27
	3. PA4196_r50
28

    
29
	the trims' strength are defined as Micron-Radians/Amp as displayed in R50 *Corrector Strength page,
30
which Changes with the trim specification.
31
See trim_strength.
32

    
33
	4. PA4187_r52, PA2060_i52
34

    
35
	These two pas are ready to merged into one	(PA4187_r52).
36
	The algorethm behind is based on a solution of 		simultaneous linear equations for non-coupling 	linear system.
37

    
38
see NoteBook page.

	5. One(or few) user pas:

42
	PA1976_i49: Ming-Jen
43

    
44
	PA4078_i128, PA4115_i129, PA4178_i130: Bruce

	These two pas involve some data transfer tasks.
51

    
52
	1. PA1793_i78
53
	Instructions to transfer mad lattice tape output data into ACNET database. Ming-Jen has already done the last transfer.
54

    
55
	2. PA4078_i128
56
	Instructions to transfer MRV radiation survey data into ACNET database.
