sensin has two buttons, Quit and Done. Clicking on the Quit button exits sensin without writing an input file. Clicking on the Done button exits after generating an output file pte.nml.name [section 4] which contains all of the entered information, along with a few values which sensin does not currently manipulate. These can be changed by directly editing the pte.nml.name file.
There are three cycle fields, marked with the circular arrows. Clicking on them changes the selection. The coordinates can be either celestial (RA/Dec) or galactic (l,b), and can be entered as DMS or HMS. The RA: and DEC: fields at the top display the current pointing in degrees, and cannot be modified directly.
There are many fields with numeric values which can be modified. SunView does not actually recognize numeric values, so these are in fact text fields, so they sometimes behave oddly. The easiest way to change them is to double or triple click to select the whole field and then to hit the cut key, deleting the value. Then type in the new value, and hit return. After you hit return, sensin converts the text field to a number, and does the appropriate calculations, and updates the approriate fields. It is important to hit return after changing each field. If you modify one field, and then another, and only then hit return, the changes in the first field will not be recognized.
Each coordinate has three fields, for either DMS or HMS. You can enter fractional degrees (hours) into the degree (hours) field. For example, if it displays 0 0 0.00, and you enter 3.5 into the first field, after you hit return, it will display 3 30 0.00. Each time you hit return, the RA and DEC values at top are recalculated and redisplayed.
The start time and stop time are displayed and modifiable as both YMDHMS and TJD (truncated julian day). The interval entered should fall wholly in a single exposure history file.
There are ten energy ranges for which the sensitive areas will be calculated. They consist of a low value, a high value, and a spectral index. They default to the standard energy ranges, and an index of 2.0 (the indices are positive). The index is only used for averaging the sensitive area over the energy range. The numbers from 1 to 10 on the left side cannot be modified.
