SLC_par_pt

ANSI-C program: SLC_par_pt.c

NAME
SLC_par_pt - read/write record of SLC/MLI parameter stack

SYNOPSIS
SLC_par_pt <SLC_par> <pSLC_par> <SLC_rec_num> <rw_flag>

<SLC_par>	SLC/MLI parameter file (enter - for output to stdout)
<pSLC_par>	stack of SLC/MLI parameters (binary)
<SLC_rec_num>	record number in the stack of SLC/MLI parameters (starts with 1)
<rw_flag>	read/write flag (0: read from pSLC_par 1: write to pSLC_par)

EXAMPLE
SLC_par_pt 08560.rslc.par testsite.ppar 4 1

Writes the SLC parameter file 08560.rslc.par (ascii) into record 4 of the stack of SLC parameters testsite.ppar (binary).

SLC_par_pt - testsite.ppar 5 0

Reads record 5 of the stack of SLC parameters testsite.ppar and writes it to standard output.

INSTALLATION
Source code SLC_par_pt.c in ./IPTA/src, executable version SLC_par_pt in ./IPTA/bin

DESCRIPTION
The use of point data stacks is an important element of the IPTA. Registered SLC data at the selected points are stored in such a point data stack with each record corresponding to an SLC image. SLC parameters for each record (SLC image) are organized in a stack of SLC parameters. This stack is in binary format and contains for each record the parameters of the SLC/MLI parameter file.

SLC_par_pt supports the transformation between the individual SLC/MLI parameter files and the stack of SLC parameters (binary).

SLC_par_pt permits to write the parameters of an individual SLC/MLI parameter file to the indicated record of a stack of SLC parameters. It is important to use the identical order in the SLC data stack and in the SLC parameters stack (i.e. the same record number should refer to the same image).

SLC_par_pt also permits to extract the SLC parameters of an indicated record of the stack of SLC parameters and to either write these parameters to an individual SLC/MLI parameter file (ascii) or to print the parameters to the screen (standard output) by indicating "-" instead of a SLC/MLI parameter file name.

The record numbers start with 1. The number of records corresponds to the highest record number.

If a new stack name is indicated the stack is created. Indicating a record number larger than the highest record number of the indicated stack results in an increase of the stack size.

Typically, the co-registered SLC (*.rslc) are in the SLC data stack. Consequently, the SLC/MLI parameter files of the co-registered SLC (*.rslc.par) shall be written to the stack of SLC parameters.

The reference SLC (SLC used as reference in the co-registration, SLC used as reference in the interferometric analysis) does not need to have a specific record number.

The SLC parameters contain information on date and time, geometry, format, processing parameters as the Doppler Centroid, and state vectors of the SLC images.

OPTIONS
