| DX | Interval identifier for the first independent variable (real number).
It is the interval between two successive values of X1
if this interval is uniform, i.e. if
X1(i+1)-X1(i) = X1(i)-X1(i-1)
for all i such that 1 < i < NX(m). For a non-uniform interval, DX = 0. |
|
| LENX | Length (number of characters) of X2. Not more than 132 characters long. | |
| XNAMEs | Name and unit of the sth independent variable. Not more than 132 characters long. | |
| NV | Number of primary dependent variables. Note that the NASA Ames checking programme does not accept NV=0. | |
| NAUXV | Number of auxiliary dependent variables, including NX. | |
| NAUXC | Number of auxiliary variables which are character strings. | |
| VSCALn | Scale factor (real number) for the nth primary variable. VSCALn is the number by which the recorded values of Vn must be multiplied in order to convert it in the unit of measure specified in VNAMEn (see below). If the nth primary variable is not rescaled, then VSCALn = 1. | |
| VMISSn | Missing value identifier for the nth primary variable (real number). VMISSn is a number indicating missing or erroneous values in the record of the nth primary variable. It must be larger than the maximal "good" value of Vn. | |
| VNAMEn | Name and unit of the nth primary dependent variable. VNAMEn must not be more than 132 characters long. The unit specified in VNAMEn must be the unit of VSCALn*Vn. | |
| ASCALa | Scale factor for the ath auxiliary variable,
(0 < a < NAUXV-NAUXC+1). ASCAL1 is an integer (usually 1). For 1 < a < NAUXV-NAUXC+1, ASCALa is real. ASCALa is the number by which the recorded values of Aa must be multiplied in order to convert it in the unit of measure specified in ANAMEa (see below). If the ath auxiliary variable is not rescaled, then ASCALa = 1. |
|
| AMISSa | Missing value identifier for the ath auxiliary variable.
AMISSa indicates missing or erroneous values in the record of
the ath auxiliary variable. AMISS1 is an integer and for 1 < a < NAUXV-NAUXC+1, AMISSa is a real number. In these 2 cases, AMISSa must be larger than the maximal "good" value of Aa. For NAUXV-NAUXC < a < NAUXV+1, AMISSa is a character string. In this last case, AMISSa could in principle be any character string of length inferior or equal to LENAa. Actually, the NASA Ames checker associated to the BADC File Uploader, that has been written by the authors of the NASA Ames Format Standard, will compare the ASCII values of the initial characters of Aa and AMISSa. The file will be rejected if the ASCII value of the initial character of Aa is found to be larger than the ASCII value of the initial character of AMISSa. The user is therefore advised to use values of AMISSa starting with z in lower case (for example, zzzzzz), since z has the highest ASCII value of all alphanumeric characters. |
|
| LENAa | Length (number of characters) of Aa for
NAUXV-NAUXC < a < NAUXV+1. For 0 < a < NAUXV-NAUXC+1, LENAa is not defined. |
|
| ANAMEa | Name and unit (except for a = 1) of the ath auxiliary dependent
variable.
ANAME1 = NUMBER OF VALUES OF THE BOUNDED INDEPENDENT VARIABLE. ANAMEa must not be more than 132 characters long. For 1 < a < NAUXV-NAUXC+1, the unit specified in ANAMEa must be the unit of ASCALa*Aa. |
VSCAL, VMISS and VNAME must be listed in the same order as the one in which the primary variables are recorded in the data section (n ranging from 1 to NV).
Similarly, ASCAL, AMISS and ANAME must be listed in the same order as the one in which the auxiliary variables are recorded in the data section.
