... Standard-star files, however, must also have the standard photometric values (in place of the rough MAG column). The column label should be the usual name of the magnitude or index in the column, e.g., V or U-B or c1; see Table . ... MIDAS table files do not distinguish between upper and lower case in column labels. Thus, while it is possible to use 'u-b' as a column label for the uvby system, it cannot be distinguished from 'U-B' by programs or MIDAS procedures that read these files. ...

SAOtng supports FITS files internally, so that a standard FITS image file can be sent directly to SAOtng for display using XPA: xpaset SAOtng Also, when a new file name is sent to SAOtng, the program checks the first 2880 bytes of the file to see if it is a FITS file and if so, processes it accordingly. Support for other image file formats (or any other image format) is added to SAOtng by writing two external file access programs: . ... The command-line of the image section program . ...

The NTP standard specifies an extension which provides cryptographic authentication of received NTP packets. ... The specification allows any one of possibly 4 billion keys, numbered with 32-bit key identifiers, to be used to authenticate an association. ... In the case of MD5, the keys are 64 bits (8 bytes). xntpd reads its keys from a file specified using the -k command line option or the keys statement in the configuration file. ...

Only output the standard header section. printhdrV can be used in conjuction with the stripVme (1l) and grep (1) programs to dump the headers of datataking tapes to the screen or a file. ...

Using the free source form it is not permitted to have comments starting with a C or a * in column 1. This would be a violation of the free format. ... An advantage compared with earlier Fortran standards is that the standard now requires that the compiler can signal if the user deviates from the permitted standard. It is required that a Fortran 90 compiler can signal . ... It has to be possible to ask the program to signal for any extensions outside the Fortran 90 standard. ...
