Subject:
GRW/CSPHOT/M1 - Obstruction in collimator tube
DataStreams:grwcsphottotalpfn1M1.a1, grwcsphotsizeM1.a1, grwcsphotcoarsepfn1M1.a1,
grwcsphotaotfiltM1.a1, grwcsphotppM1.a1, grwcsphotfinepfn1M1.a1, grwcsphotalm1duboM1.a1,
grwcsphotaotM1.a1, grwcsphotalmM1.a1, grwcsphotaotfiltqaM1.a1
Description:
Data are suspect. There is a discrepancy between the 1640 channel and the other channels. 
The discrepancy is possibly related to the intermittent obstruction (a lizard) found in 
the collimator tube. There may also be ongoing degradation of the instrument possibly 
related to the lizard activity and deposits.
Suggestions: 
Use co-located MFRSR data
