| Keyword TIMEDEL missing in Input File | error | |
| The TIMEDEL keyword is missing in the timeseries FITS file, which is necessary to determine the binning factor of the data | ||
| Null or negative Bin Width in Input File | error | |
| The TIMEDEL keyword is null or negative in the timeseries FITS file. This should be a positive value. | ||
| Different number of columns between RATE, ERROR, BACKV and BACKE | error | |
| There should be one RATE column, one ERROR column, one BACKV column and one BACKE column for each lightcurve in the input timeseries FITS file. | ||
| Different number of rows in columns between RATE, ERROR, BACKV and BACKE | error | |
| The columns in the timeseries FITS file have differing lengths. They should all be the same length | ||
| Number of light-curves contained in a file must not exceed 9 | error | |
| There are too many lightcurves contained in the timeseries FITS file - 9 is the maximum allowed. | ||
| No data point received | error | |
| Less than two good values in the timeseries FITS file. | ||
| Negative count rates in Input File | error | |
| The total count rates are negative and should not be. | ||
| Negative background values in Input File | error | |
| The background count rates are negative and should not be. | ||
| Require new output file name | error | |
| newoutset should be set to yes and a new output filename given or screen should be set to yes | ||
| Can not carry out two distribution KS test and chi-squared test | error | |
| The program is limited to the carry out only the cumulative probability
function of the observed net count distribution and the cumulative
time distribution with the other variability tests | ||
| Not enough bins to process variability tests | warning | |
| Less than two good values remain after removing those bins outside of the GTIs and those bins with both source and background values that are null or negative. Hence it is impossible to carry out the variability test.
corrective action: Use a different input file | ||
| Keyword CONTENT missing in Input File | warning | |
| No valid CONTENT keyword is contained in the header of the input timeseries FITS file which could indicate that there is a problem with the input timeseries FITS file.
corrective action: Verify that this is a valid fits file | ||
| CONTENT parameter for input file is ... | warning | |
| The CONTENT keyword is not the expected parameter.
corrective action: Verify that this is a valid fits file | ||
| Keyword HDUCLASS missing in Input File | warning | |
| The keyword is missing in the input timeseries FITS file which could indicate that there is a problem with the input timeseries FITS file.
corrective action: Verify that this is a valid fits file | ||
| HDUCLAS is not equal to OGIP | warning | |
| The keyword is not as expected in the input timeseries FITS file which could indicate that there is a problem with the input timeseries FITS file.
corrective action: Verify that this is a valid fits file | ||
| HDUCLAS1 is not equal to LIGHTCURVE | warning | |
| The keyword is not as expected in the input timeseries FITS file which could indicate that there is a problem with the input timeseries FITS file.
corrective action: Verify that this is a valid fits file | ||
| HDUCLAS2 is not equal to TOTAL | warning | |
| The keyword is not as expected in the input timeseries FITS file which could indicate that there is a problem with the input timeseries FITS file.
corrective action: Verify that this is a valid fits file | ||
| Keyword TSTART missing in Input | warning | |
| The keyword is missing in the input timeseries FITS file which could indicate that there is a problem with the input timeseries FITS file.
corrective action: Verify that this is a valid fits file | ||
| Keyword EXPOSURE missing in Input File | warning | |
| The keyword is missing in the input timeseries FITS file which could indicate that there is a problem with the input timeseries FITS file.
corrective action: Verify that this is a valid fits file | ||
| Null or negative exposure time in Input File | warning | |
| The EXPOSURE keyword is null or negative in the timeseries FITS file. This should be a positive value.
corrective action: Verify that this is a valid fits file | ||
| Keyword TSTART missing in GTI File | warning | |
| The keyword is missing in the input GTI FITS file which could indicate that there is a problem with the input GTI FITS file.
corrective action: Verify that this is a valid fits file | ||
| Keyword TSTOP missing in GTI File | warning | |
| The keyword is missing in the input GTI FITS file which could indicate that there is a problem with the input GTI FITS file.
