1-D (htr) spectrograms can be created using the TIDE Custom Plot web-interface. There is a Custom Plot Page for each type of htr spectrogram:
| Plot type | Custom Plot Link |
| eshtr | Energy / Spin Angle htr Plots |
| esphtr | Energy / Spin Angle / Polar Angle htr Plots |
| ehtr | Energy htr Plots |
| shtr | Spin Angle htr Plots |
| phtr | Polar Angle htr Plots |
All of the prompts are designed to get the input used to create the lz_parm parameter file and the tide_lz list file that contains the start and stop times and a list of input files associated with that time range. The webpage is filled in with some defaults that you can change.
The first menu item for all five plot types asks for the start and stop date range of the data to be processed. The date can be enter as year/day-of-year (yyyydoy) or year/month/day-of-month (yyyymmdd). The year must be four digits. Time is entered in hour/minute/second (hhmmss). Seconds must be included even if they are 00. Do not use any spaces. Use the tab key or the mouse to move from one date/time field to the next.
The next item is for the mass(s) to be plotted. If the mass is Stops, enter the mass-to-charge ratio of the ion used in the flux calculation. For eshtr and esphtr plots, only one mass can be selected. For ehtr, shtr, and phtr plots, up to 5 masses can be selected. There will be one mass per panel on the plot.
Next you are asked what flux unit (usually energy flux) to use and the minimum and maximum flux values to use on the colorbar.
Next you enter whether to calculate and plot color based on the sum, the average, or the maximum count. You have the option to limit the range of the energy, spin angle, and polar channels used in the calculation.
The remaining menu items determine what mask to use, whether or not to correct the mask subtraction (See TIDE Ion Mask File for details), whether or not to use the sector sensitivity correction (See Instrument Calibration for details), and whether or not to subtract the minimum count (See Minimum Count Subtraction for details).
Once you have made all the changes you want to the default plot settings Submit request. To clear the form Reset Form. Once you Submit request, the web server queries the File Location Table to get a list of the input files needed for the processing and where they are stored. This information is used to create the tide_lz list file. The information provided via the menu is used to create the parameter file via lz_parm. The web server uses the parameter and list files as input to the idl version of tide_lz (@run_tide). Once the processing is completed and the postscript, gif, and pdf files are created, the gif image is returned as a webpage. Any or all of the plot files can be downloaded from this webpage. The plots files remain in a staging area for three days. They can also be downloaded from the staging area. The web uses the job process id as the optional ext2 filename extension.
