This file contains data from the Low Energy Telescope II (LET-II) channels R15AD, SR2BD, and R15BD. The data cover 1979-08-31 to 1979-09-03. This is a space-delimited ASCII table with fixed width columns. The data consist of a time column followed by a flux and flux uncertainty for each of the data channels. This file includes the following channels: Channel 1 = (R15A / 1.500E-02) - (R15D / 1.500E-02) R15A = S1(1).^S2.^S2(A).^S3 R15D = S1(4).^S2.^S2(A).^S3 Channel 2 = (SR2B(9) / 1.500E-02) - (R15D / 1.500E-02) SR2B(9) = S1(6).^S2.^S2(A).^S3(9) R15D = S1(4).^S2.^S2(A).^S3 Channel 3 = (R15B / 1.500E-02) - (R15D / 1.500E-02) R15B = S1(2).^S2.^S2(A).^S3 R15D = S1(4).^S2.^S2(A).^S3 Individual detectors in LET-II subsystem are identified by S1, S2, S3, and S2(A), the annular guard detector. The subscript in parentheses of a detector identifier refers to the trigger threshold on that detector. Several detectors defining a flux channel are in coincidence unless the symbol '^' preceding the detector identifier indicating that detector is in anti-coincidence.
