4.119.1 SCIA RD LADS
Identifier SCIA RD LADS
Purpose read Geolocation of the state records
Usage nr dsr = SCIA RD LADS( fd, num dsd, dsd, &lads );
Input FILE *fd : stream pointer
unsigned int num dsd : number of DSDs
struct dsd envi dsd : structure for the DSDs (A.6)
Output struct lads scia **lads : geolocation of states (C.10)
Returns number of data set records read (unsigned int)
error status passed by global variable “nadc stat”
Comment none

4.120 SCIA RD H5 MEM
Identifier SCIA RD H5 MEM
Author R.M. van Hees
Language ANSI C
Purpose read table for Reticon non-linearity correction
Usage SCIA RD H5 MEM( &mem );
Output struct scia memcorr *mem : (C.2)
size t dims[2] : dimension of matrix (hdf5 definition)
float **matrix : memory correction matrix

size t dims[2] : dimension of matrix (hdf5 definition)
char curve[8192] : index to correction curve
float **matrix : non-linearity correction matrix
Returns Nothing
Comment You need to release allocated non-linearity, use SCIA FREE H5 NLIN
