This file gives the (symmetric) covariance matrix, truncated at L=5, in ASCII format. It was created from the binary version "jggrx_0900d_shb_l50.dat". Each line gives the matrix elements along each row, with the same parameter ordering as for the "jggrx_0900d_shb_l05_coefficients.asc" file. There are 33 lines/rows/parameters, and the format is "%20.13e " repeated 33 times. Line feed and carriage return characters complete the line (DOS format).
