README: WF/PC-1 returned filter spectral profiles

Measured: December 1994

The following file naming conventions are used for the 
passband and blocking directories:

faaab_c.dat

f   - filter
aaa - central wavelength
b   - n, w, or m for narrow, wide or medium
c   - 1-5 indicates number of the passband spectral scan.  
    - b indicates blocking curve on a logarithmic scale.

The passband has been measured at five positions on each 
filter.  The scan number indicates the position on the 
filter (and in the WFC field of view) as follows:

     -----------
    |WF2  1  WF1|
    |     |     |
    |4----5----2|
    |     |     |
    |WF3  3  WF4|
     -----------
 
Scan 5 is at the center of the filter, corresponding to 
the pyramid apex.  The other four scans are at the middle
of each side of the filter, corresponding to the pyramid
ridges separating the four cameras, as indicated.

Blocking curves are taken at the center of the filter only.
