Input/Output of Tables

The exchange of table data to and from the MTS is mainly done through standard ASCII files. This makes it easy for any program to get data from the MTS and to transfer data into it. Thus, output files from text editors and Database systems containing table data in a fixed format can directly be transferred into the MTS format.

Conversion between the ASCII data file and the table is defined by a format file (see section 5.7). If the format file does not exist, the conversion is done automatically via list-direct input in free format. In this case only REAL*4 and integer data, without NULL values are allowed.

 

Table 5.1: Conversion between ASCII Files and MIDAS Tables

Command	Description
CREATE/TABLE	Convert from ASCII files to MTS format
PRINT/TABLE	Transfer MTS information to the ASCII file assigned as output. The printer is used by default.

 

Normally, table files should be copied to magnetic tape in the FITS format for tables (Harten et al., 1985, Mem.S.A.It., 56, 437) to make it easy to read them again on other computers. The conversion to FITS is done by the MIDAS command OUTTAPE; FITS tables are loaded onto disk by the command INTAPE.
