### Hey,
### I send you the 4m filter functions. I convolved the sensitivity
### functions with QE, extinction, etc, so that different files include
### different effects:
###
### i4m_1.dat, r4m_1.dat: sensitivity alone, measured with the filters in CTIO.
###
### i4m_2.dat, r4m_2.dat: sens. + quantum efficiency of CCDs
###
### i4m_3.dat, r4m_3.dat: sens. + QE + aluminun reflectivity
###
### i4m_4.dat, r4m_4.dat: sens. + QE + aluminun reflectivity + sky lines
###
### i4m_5.dat, r4m_5.dat: sens. + QE + aluminun reflectivity + sky lines + extinction. 
### This is the final throughput, the same files I sent to Brian Barris for BATM.

### Gajus,
###
### I don't know what version of the filters you were using, because I
### remember at some point sending you filters and emails saying if they
### are multiplied by lambda or not. This is my mistake since I never
### write headers in the filter files, sorry!.
###
### I send you the files again, this time with minimal information in the
### header, at least is says they are multiplied by lambda.
###
### [THESE TWO FILES ARE IN THIS DIRECTORY AS R_4m.dat AND I_4m.dat  --sj]
