pint.models.jump.DelayJump
- class pint.models.jump.DelayJump[source]
Bases:
DelayComponent
Phase jumps
Parameters supported:
Name / Aliases
Description
Kind
JUMP {flag} {value}
s
Note
This component is disabled for now, since we don’t have any method to identify the phase jumps and delay jumps.
Methods
add_param
(param[, deriv_func, setup])Add a parameter to the Component.
d_delay_d_jump
(toas, jump_param[, acc_delay])get_params_of_type
(param_type)Get all the parameters in timing model for one specific type.
get_prefix_mapping_component
(prefix)Get the index mapping for the prefix parameters.
is_in_parfile
(para_dict)Check if this subclass included in parfile.
jump_delay
(toas[, acc_delay])This method returns the jump delays for each toas section collected by jump parameters.
match_param_aliases
(alias)Return the parameter corresponding to this alias.
Print help lines for all available parameters in model.
print_par
([format])- param format:
Parfile output format. PINT outputs the 'tempo', 'tempo2' and 'pint'
register_deriv_funcs
(func, param)Register the derivative function in to the deriv_func dictionaries.
remove_param
(param)Remove a parameter from the Component.
set_special_params
(spcl_params)setup
()Finalize construction loaded values.
validate
()Validate loaded values.
validate_toas
(toas)Check that this model component has TOAs where needed.
Attributes
Return all the aliases and map to the PINT parameter name.
category
component_types
Return the free parameters in the component.

- jump_delay(toas, acc_delay=None)[source]
This method returns the jump delays for each toas section collected by jump parameters. The delay value is determined by jump parameter value in the unit of seconds.
- print_par(format='pint')[source]
- Parameters:
format (str, optional) – Parfile output format. PINT outputs the ‘tempo’, ‘tempo2’ and ‘pint’ format. The defaul format is pint. Actual formatting done elsewhere.
- Returns:
str
- Return type:
formatted line for par file
- add_param(param, deriv_func=None, setup=False)
Add a parameter to the Component.
The parameter is stored in an attribute on the Component object. Its name is also recorded in a list,
self.params
.- Parameters:
param (pint.models.Parameter) – The parameter to be added.
deriv_func (function) – Derivative function for parameter.
- property aliases_map
Return all the aliases and map to the PINT parameter name.
This property returns a dictionary from the current in timing model parameters’ aliase to the pint defined parameter names. For the aliases of a prefixed parameter, the aliase with an existing prefix index maps to the PINT defined parameter name with the same index. Behind the scenes, the indexed parameter adds the indexed aliase to its aliase list.
- property free_params_component
Return the free parameters in the component.
This function collects the non-frozen parameters.
- Return type:
A list of free parameters.
- get_params_of_type(param_type)
Get all the parameters in timing model for one specific type.
- get_prefix_mapping_component(prefix)
Get the index mapping for the prefix parameters.
- is_in_parfile(para_dict)
Check if this subclass included in parfile.
- Parameters:
para_dict (dictionary) – A dictionary contain all the parameters with values in string from one parfile
- Returns:
Whether the subclass is included in the parfile.
- Return type:
- match_param_aliases(alias)
Return the parameter corresponding to this alias.
- Parameters:
alias (str) – Alias name.
Note
This function only searches the parameter aliases within the current component. If one wants to search the aliases in the scope of TimingModel, please use
TimingModel.match_param_aliase()
.
- param_help()
Print help lines for all available parameters in model.
- register_deriv_funcs(func, param)
Register the derivative function in to the deriv_func dictionaries.
- Parameters:
func (callable) – Calculates the derivative
param (str) – Name of parameter the derivative is with respect to
- remove_param(param)
Remove a parameter from the Component.
- Parameters:
param (str or pint.models.Parameter) – The parameter to remove.
- validate()
Validate loaded values.
- validate_toas(toas)
Check that this model component has TOAs where needed.
